I did two test installs on Sunday. First, I did a simple install and
setup /home on a logical volume made up of sda3 and hda2. It failed to
boot properly becuase ide_disk was not loaded and the vg could not be
brought up.
I then reinstalled the exact same way, but placed ide_disk in
/target/etc/modules prior to the reboot - everything worked fine.
