It doesn't really have an effect, because even without this, the noise
floor calibration fails anyway.  I suspect by the time it gets in this
state the device is just hung generally.

So, I can't sustain a connection long enough to do iperf.  I got numbers
from madwifi though :)

Seems when it gets a big hunk of data the device barfs.  When I'm doing
something like ssh or just browsing a little, it's annoying but still
useable because most of the time it'll disassociate with the AP for a
few seconds, reassociate, and it's working again.
