Well, the lower 4 slots are controlled by a PCI bridge, I can't move 
the USB card into one of the upper slots because the SCSI/Ethernet 
board doesn't fit anywhere else and the graphics board has a weird 
firmware problem that keeps it from working behind a PCI bridge...

I'll try it without SCSI/Ethernet, although that can only be temporary.
