Is your PS/2 device on your motherboard? Who manufactures the board? Is
there any other device using the PS/2 ports interrupt or IO address space?
(IRQ 12, I believe, and 0x0060 and 0x0064 for IO). I believe the chip you
should have is an i8042, or some sort of hardware emulation in a Super IO

If you look in [linux-src-root]/drivers/char/psaux.c, you will see that
there is a line which you may need to uncomment to initialise your mouse.
perhaps this will aid you.

Good luck!
