Hrm. I remember installing a 64-bit QFE PCI card in a Sun with 32-bit PCI
slots and it worked fine. Did you check for the presence of the gap near
the front on the edge connector which would indicate whether it's a 3.3V or
5V PCI card? If the motherboard has a small piece of plastic which mates
with that gap, the motherboard supports 3.3V cards only. But it sounds like
you have a 5V motherboard. I can't remember if 5V implies 3.3V; I don't
think it does.
As far as I'm aware, most 64-bit PCI cards are backwards-compatible with
32-bit PCI host bridges, someone else on the list feel free to correct me
if I'm wrong.
