For a card with a bus interface of that type, I'd hope that the card
is typical PCI64 in that it will work properly in 3.3V PCI32 slots.

That aside, yes, I would expect that some embedded systems will start
to grow 64-bit PCI over the next few years, but it seems a bit further
off before we see Intel or AMD pushing the power consumption of their
high-end CPUs really far down.  (Yeah, batteries in the newer dual
core laptops are suffering, but "who cares" in their eyes?  ;)

Right, whereas I mean *really* low power systems for truly embedded
usage.  In the NetBSD world, that's a much larger % of users than in
the rest of the OS worlds.
