i've used/seen cards with these prefixes:
00:e0:29 - smc
00:02:2d - orinoco/wavelan cards (lucent/agere)
however, there's nothing to stop the vendor from using a given prefix
for wired cards as well. more to the point, it's relatively trivial
to change the hardware address of the card, so all bets are off (read
as: mac address filtering is useless).
