Sheesh. I know for a fact that on my MSI KT400-based board the USB
keyboard will *not* be hard reseted on reboot or even reset. Direct
result -> USB keyboard is dead if the OS hangs before gracefully
resetting it in the shutdown sequence (or if you use an OS unaware of
this fact, like linux 2.5 was before I bugged the USB maintainer).

On this kind of board you have to teach BIOS magic to your kernel or
systematically cold restart. I wouldn't be surprised at all if the hack
that was put in 2.6 only worked on semi-standard x86, and not on exotic
hardware like the Epia or x86_64.

Either way the guy who okayed this partial reset sequence should be shot
- with the power button taken over by acpi nowadays you'd better have a
readily accessible PSU switch or you'll end up yanking the power cord
every single time your OS does not do the software resetting for the
BIOS (as in Windows crashing, which should be a mainstream problem
MSI/VIA should care about).

Cheers,
