I haven't had occasion to stop by my friend's place, but it looks like
a lot of these AMD 5x86 machines are popping up... I happen to have one
on loan from another friend who wants me to configure Windows 98, set it
up with an internet connection, etc... I haven't opened it up to see if
it's the same motherboard as the one that I originally reported as
causing problems, but it seems similar: UMC chipset, PCI slots, AMD 5x86
CPU, no PS/2 mouse port, and NetBSD's opms probe locks up the keyboard.

I applied your patch, but it didn't help :( Here are the boot messages
(with "options PCKBCDEBUG"):
