lib80211 was _included_ in the kernel already but I recompiled to make
it a module, just to make sure it was not the problem.
r...@mini ~ # grep CONFIG_LIB80211

No lib80211 yet... I will load it to be certain.

Nothing changed... Again, the Broadcom driver is helpless.
Also note all of this was made after a _warm_ boot. Do you want me to
try everything from a cold boot?
