64-bit PCI cards will work in a 32-bit PCI slot. I've got a four-port 64-bit
Ethernet card in a 32-bit PCI slot in one of my systems.

As for motherboards with 64-bit PCI slots, there are several. First off, there
are several Alpha motherboards with 64-bit PCI slots. Then there are the boards
for the Pentium III processors with the Serverworks chipsets. There are also
motherboards for Athlon-MP processors with 64-bit PCI slots (some of which are
also 66MHz slots). I know there were earlier motherboards for Pentium II and
Xeon processors with 64-bit PCI slots, but they weren't advertised in the usual
places as they were more of a specialized board, but they were advertised in
some areas.
