I would say your BIOS is buggy. You may try declaring 12 IRQ dedicated to ISA in
BIOS setup (should be somewhere in PNP/PCI section). Then, PCI cards will not
"take" IRQ 12. Also, make sure the OS IS NOT declared PNP/ICU in the same
section.
The keyboard is stuck because PS2 port is stuck (causes both mouse and keyboard
to lock up). There is also a known problem with X, when mouse gets beserk. In
the case of PS2 mouse, it causes the keyboard to lock up. To avoid that, you can
run gpm driver with "-r" option, and configure X to use /dev/gpmdata device and
MouseSystems protocol.
I hope that helps.
