in can confirm this. It happened either when upgrading
from initramfs-tools 0.69ubuntu26 to 0.85dubuntu2
or from initramfs-tools 0.85dubuntu2 to 0.85dubuntu3

both updates were done the same day.

I can also confirm Cedric Schieli's workaround:

 sudo vi /usr/share/initramfs-tools/scripts/local-top/udev_helper
comment out modprobe -q ide-generic
then run
sudo update-initramfs -u -k 2.6.20-2-generic
or whichever kernel is not booting anymore
then uncomment modprobe... so you get a vanilla version of /usr/share/initramfs-tools/scripts/local-top/udev_helper
