Similiar problems here after my upgrade to 1005D. Linux somehow kills
the keyboard if I start the box without a PS/2 mouse connected. I have
another machine (these are both 2.4.1) which is a much older K6-233, and
it too kills the keyboard if no mouse is present. Keyboard works at LILO
prompt but is dead by the time I get to login. GPM doesn't work for me
