Since the first one, I disabled autoloading of the module during boot and
removed the wireless device from the udev startup scripts and added it to a
udev blacklist,  so that I could load it manually without unloading first.
So maybe there was something in the startup scripts causing this (i.e. the
option with disable_hw_scan somewhere). I just deleted all related files
to "start cleanly" so I didn't keep a backup that I can check. :( Looks
like the dmesg output doesn't show which options the module was loaded
with, maybe this would be handy in future?
