You can find the answer in the wiki: the idea is that one does not use /etc/modprobe/blacklist.conf.
Instead, say you want to blacklist pcspkr. You create a pcspkr.conf file in /etc/modprobe and put blacklist pcspkr inside. Then run
depmod -ae && update-initramfs -u

Couple things:
1) Biggest thing is to disable any unnecessary services. mdmonitor, pcscd, isdn iscsi hplip and hidd are pretty safe to disable to start at boot for the average workstation. Unless you're exporting nfs (this doesn't affect mount exports from others), you can disable any service beginning in "rpc" and any portmap/rpcbind services. "gpm" is ...

Update2:
Forgot you posted the tar ball. Too bad. Anyhow, did a test on your .mod files
by using the below code and:
./grum_lic_test32 evan_teitelman/boot/grub/i386-pc/*.mod
which yielded the following error:

bufio.mod License: LICENSE=GPLv3+ OK
cacheinfo.mod License: LICENSE=NONE_FOUND ERR

GRUB does not have to load the whole kernel into memory. The kernel image is split into two pieces:
The real-mode kernel code, which is small and can be loaded within the 640kB threshold of available memory;
The rest of the kernel, which runs in protected mode and is loaded after the first megabyte of memory.
The bootloader only loads the real-mode ...

If you can boot on a liveCD, you can enter the fdisk -l command. It will show you all the partitions detected on your disk(s).
You can then mount a partition manually with the command mount <device> <mount point>. <device> is one of the partition fdisk detects (something like /dev/sda1 for example) and <mount point> must be a ...

kexec is a mechanism by which the running kernel replaces itself by another one. An external program doing so would have to have an extremely intimate knowledge of the kernel(s) involved, and kernel-level access to everything on the machine too. Perhaps doable, but I think nobody is crazy enough to try.

First determine how much time booting does take now. For that set an arbitrary but clear point after which you consider the machine booted, and measure that. I recommend going for CPU going down to the background noise level and no more (startup) disc activity. Based on that you have something real to make comparisons instead of some vague feeling of boredom ...

An alternative method is to disable this through plymouth:
plymouth-set-default-plugin text
/usr/libexec/plymouth/plymouth-update-initrd
If you're interested in more about plymouth check out the references to it below. It's what powers the bootsplash for Red Hat based distros.

Take a look at this thread over on ubuntugeek.com titled: Boot-Repair – Simple tool to repair frequent boot problems. This tool may be able to help repair what's wrong with your HDD. Looking at the list of features this seems like the easiest way to try and repair your boot partition without getting your hands too dirty.

Your kernel lacks support for aes-cbc-essiv:sha256. “Error allocating crypto tfm” refers to the kernel's cryptographic subsystem: some necessary cryptographic data structure couldn't be initialized. Your support for cryptographic algorithms comes in modules, and you have a module for the AES algorithm and a module for the SHA-256 algorithm, but no module for ...

The kernel contains a default root partition setting, determined at compile time (you can change it in the binary image with the rdev command). You can pass an argument on the kernel command line to override this default at boot time, e.g. root=/dev/mmcblk9p42 to boot from MMC device 9 partition 42 instead of the default. The command line is passed to the ...

Turning off 3D acceleration in the VM's configuration will fix it. There's a bug with some of the packages on the CD. After installing to the VM and running updates you can turn 3D acceleration back on.
Here is the ask.fedoraproject link that I saw: https://ask.fedoraproject.org/question/10024/fedora-18-impossible-to-use-on-vmware-9/
and the bug report:
