I found a fix and diff's attached. This hack lets you boot in 'safe
mode' and seems harmless for Compaq R3000Z.
Somehow this machine shuts down when it issues 'Keyboard Interface
Test' command (0xab) to port 0x64.
It only boots in 'safe mode' because of broken nForce3/BIOS. See the
chipset section from the following link:
We may need to add this in hints as a flag (e. g.,
hint.atkbdc.0.flags) or a MIB (e. g., hw.atkbdc.disable_test).
I only verified in FreeBSD/amd64 but it should work for FreeBSD/i386
* PS: Since we have ACPI blacklist feature now, we can blacklist this
