Re: odd PS/2 keyboard fail

        Hello.  I wonder if there is an option in the bios to turn on PS/2
emulation for USB keyboards and if that's interfering with the 4.0 keyboard
driver?  My guess is that the 1.4T kernel didn't care about such things and
relied entirely on the bios to do its keyboard handling, but that 4.0 tries
to relieve the bios of its duties.  I know you're using a PS/2 keyboard,
but I'm thinking perhaps the bios is confusing the driver somehow.  If
there such an option, or something like that, I'd flip it back and forth
and see if the behavior changes.  It still might not work, but it might
change, thus throwing light on the problem.
