More news on this.  After getting 6.0-BETA2 installed from the serial
console, I found that _any_ input on the PS/2 port causes the machine to
lock up hard.  I can break into the debugger, but as soon as I hit any
key on the PS/2 keyboard, the machine locks up. I can't type anything
(even from the serial console).  The only way out is to do a hard reset.

I've tried building a custom kernel and disabling apic and acpi.
Nothing will get 6.0 to work with any locally attached keyboard.

I also found a CD of 5.4-RC3, which boots perfectly on this machine with
working PS/2 and USB keyboards.  So, I thought maybe the kbdmux was the
problem.  I reverted the kbd code to original RELENG_6 version (kbd.c
rev. 1.43 and kbdreg.h rev. 1.17), and the keyboard works once again.
Anything else I can try to debug this problem with kbdmux further?
