I've never been able to get a sufficiently accurate detailed explanation
of the problem FreeBSD has on this mobo that I could get the BIOS vendor
to fix it; (read, there isn't a fix I know of; but you should be using
the latest '1007' for other reasons).  I've avoided nForce3-150 mobos
like the plague and don't have one for looking into this.

If anyone can dive deeper into this issue, I'd appreciate it and will
work to have the vendor fix it.
