Yaird only includes the minimally needed, so if only the pata
controller was needed for the rootfs to get mounted then only drivers
for that was included.

Great. Now that you are up and running with the sata controller, try
commenting out that line again, and check if yaird is able to generate
a ramdisk for your running setup.

If not, then there's a bug in yaird (probably due to the sata driver
being somewhat broken).

We are talkning about 2.6.15 or newer, right? Not the buggily patched
2.6.12 or 2.6.8?
