oh no, it's not related to the available mac address. With ath9k you
can setup additional virtual interfaces and all with different macs
[someone has tested it with AFAIK up to 128 virtual APs or stations -
of course there are constraints and problems. The most important one
for this hardware is that all these virtual interfaces must operate
on the same channel/frequency. You can easily add a "guest network"
with just one card, as long as both networks share the same channel.

Can you please tell us, where you got this info?

Note: I know that some shops are advertising Intel's 6235 with simultaneous
dual-band capabilities. (i.e: <http://skinflint.co.uk/eu/804056>,
<http://www.heise.de/preisvergleich/804056>) [I've already asked someone
about this and got a "no"]
