No, I did indeed mean 02: (that bit is the locally administered field
for the address).

Interesting.. I would have expected this to work. Would you be able to
test this with a more recent kernel version (or compat-wireless for

That is not correct. The second address really needs to be
bssid=02:21:91:01:11:6f like I wrote.
