Wired PS/2 Keyboard and Mouse do not work in 12.04 Live CD or after fresh 12.04 install

My Wired PS/2 keyboard and mouse do not work in 12.04, either in a fresh install or from the Live CD. A USB keyboard and mouse will work. The PS/2 keyboard and mouse will work using the same hardware and a fresh 10.04 Ubuntu install or a fresh Windows 7 install.

So far I've tried running in the fresh 12.04 install:

sudo apt-get install

sudo apt-get upgrade

sudo apt-get dist-upgrade

After the apt-get upgraded the first time, I now get to the point where there are 0 items to be upgraded. Rebooted and still no PS/2 keyboard/mouse.

I've also tried adding the following lines to GRUB at boot time (the PS/2 keyboard works in GRUB)



Neither setting made any difference.

The motherboard is a Foxconn D270S Atom based motherboard. Even more interestingly, 12.04 recognizes the same PS/2 keyboard and mouse on a separate Gigabyte AM3+ based motherboard. I only have this problem on this particular motherboard with Ubuntu 12.04.

Any help would be appreciated. I bought this low-power motherboard specifically for the task of running Ubuntu 12.04 for the next five years...
