Bug Description

(Separating from bug #17366 since this is a different issue)

mizar:[/tmp/initramfs] cat conf/modules
ide-disk
ide-generic
ext2
ext3
vga16fb
fbcon
capability
vesafb
fbcon

ide-generic needs to be loaded after the PCI scan. This seems to have been
caused by:

mizar:[~] cat /etc/mkinitramfs/modules
ide-disk
ide-generic
ext2
ext3

but I don't remember creating that file, and know of no reason why I would have
done so. I see that it copies in an example in fresh installs; did the example
file contain these lines at some point in the past?

Per discussion on IRC, Warty Systems included ide and filesystem bits in the
/etc/mkinitrd/modules file. Those are now getting in the way.

<mdz> jbailey: we should explicitly exclude ide-generic, ide-disk, ext2 and ext3
from that migration
