I don't have any IDE drives and my only SATA hard drive is running in AHCI mode, but my initrd image loads the pata_atiixp module. Is it safe to disable this module? And what about the ata_generic onde?

To answer the first question: Yes

But anyway, it should be easy to generate a backup entry in your boot manager (with the original initrd and working kernel), in case something goes wrong.

To answer the second one - you can use

$ lsmod
Module                  Size  Used by

On your running systems to see, if ata_generic is loaded and if it is, which modules depend on it (look at the used by column.

In addition to lsmod, if a module is loaded, you can try rmmod pata_atiixp. If the module is loaded and is used for anything, you won't be able to unload it. – Gilles Jan 22 '11 at 18:44
Interesting, ata_generic is not being used by anything apparently. It does use libata, as does ahci, so it seems to be safe to not load both pata_atiixp and ata_generic in my case. – devius Jan 22 '11 at 18:58
