I don't think the AGP hardware is broken, but BSD can't seem to route the
interrupt correctly for the AGP port. It cause the video card to be routed to
IRQ 11 in FreeBSD, but in Windows, it is routed to irq 16. They should be the
same in both OS's, and since it works in windows, I'm assuming it's FreeBSD
that's broken.
