We had 1.2 or thereabouts running on both P90 and 486 single-board
computers (one of each on a split backplane actually). I don't remember
what exact model they were, but I think they were from Advantech, though
I don't really recommend them for anything high-quality.... We didn't
try the PCI bridges on them, but I don't see why there'd be any more
problems than with your average PC hardware! ;-)
One thing I'm getting quite interested in are the new VME64X, VME320,
and CompactPCI industrial boards. Looks like you can build a decent
computer out of CompactPCI equipment and get good performance to boot,
and not suffer without driver support, etc., though I've also heard some
of these systems are just different enough to cause hassles with drivers
too. VME64X is another story of course and would definitely require
driver work (though you could probably get started with most that have
PCI mezzanine support) but it might just have enough political advantage
over CompactPCI in the industrial and embedded computing circles to make
big inroads. VME320 could really break some speed barriers and give
CompactPCI a real run if they don't keep it too proprietary.
I'd be interested in hearing if anyone has done any work with NetBSD on
any of the PC104 boards too....
