archlinux cannot boot after replace module init with kmod

Question

I install archlinux (latest iso from the repository), then I install broadcom-wl and connect to the network to run

pacman -Syu

everything is OK, then I run

pacman -Syu

again, it ask that shall I replace module-init with kmod I type yes, and archlinux says

rc.conf and profile.d/locale.sh conflicts.

I found the -f option will force replace the configuration So I try

pacman -Syuf

After i reboot It shows that

cannot find device /dev/sda7

then a recovery shell is displayed.

I can never boot archlinux again! I check the menu.list from windows xp, found it OK,

# (0) Arch Linux
title  Arch Linux
root   (hd0,6)
kernel /boot/vmlinuz-linux root=/dev/sda7 ro
initrd /boot/initramfs-linux.img

# (1) Arch Linux
title  Arch Linux Fallback
root   (hd0,6)
kernel /boot/vmlinuz-linux root=/dev/sda7 ro
initrd /boot/initramfs-linux-fallback.img

# (2) Windows

This truly is a hard one, but I went through it aswell. Also it is no grub problem!

1. create an arch live stick and boot it

2. mount your root partition to /mnt on the live stick

3. mount your /proc partition to /mnt/proc using mount -t procfs proc /mnt/proc

4. mount your /sys partition to /mnt/sys using mount -t sysfs sys /mnt/sys

5. mount your /dev partition to /mnt/dev using mount -t tmpdevfs dev /mnt/dev

6. mount your /boot partition to /mnt/boot

7. chroot into /mnt using chroot /mnt

8. now perform pacman -Syu and watch your kernel being built.

9. finally type exit and reboot. remove your stick and boot into your now working arch linux

I hope this works for you as well as it did for me :)
