I'm not sure if my earlier email(s) made it to the list -- the gtalug
archive is a few days old.  So at the risk of repeating myself, one
factor to consider is that your regdomain is also constrained by your
device in some cases.  I do not know if this is true for rt2x00, but
it is for at least Atheros and Intel.

You can see what your device allows with 'iw phyX info'

Also, the warning previously posted looks like a kernel bug of some sort.
