With this test (transfer via ssh to cold-booted b43) i also get some
interesting results:

[ 2140.029809] b43-phy0 debug: Using hardware based encryption for keyidx: 0, mac: 00:02:84:7d:3c:02

[ 4565.170928] wlan0: disassociated from 00:02:84:7d:3c:02 (Reason: 1)

Then repeated associations and deassociations until i unload the driver.
Reloading brings functionality back.

I need to do more tests to say if i consistently see the same time interval
(between starting and failing) in this test.
