This may or may not be a solution, but it should be mentioned.
I installed kubuntu on an IBM laptop that previously ran gutsy just fine.
The sound wasn't working and I couldn't get the wireless working.
I added the wireless modules into /etc/initramfs/modules and then ran
update-initramfs thinking that if the modules were available at boot time,
the wireless card would be seen.... but it appeared that it was already seen
at boot so I didn't have much expectation of fixing anything.
I rebooted, and low and behold I had both sound and wireless.
Methinks there might be something wrong with the distributed initrd.
It wouldn't hurt to make a copy of your current initrd file and then run:
update-initramfs -k all -c
which will create a new initrd file. Then reboot.
