Whats the first thing anyone that might help you gonna need???

Motherboard details, chipset, memory, etc etc... :)

I have two different amd64 systems, both have run FreeBSD 6 RELEASE,
and one is running CURRENT, so its not the architecture in general thats
broken.

One last resort you might try, boot Failsafe, I've had that work when
just turning off ACPI doesnt.

Good luck,
