IIRC this is a workaround for cards that have their firmware in RAM
(i.e. almost all hostap cards). They loose their firmware on suspend and
our scripts don't reload it. This is actually a bug in our firmware
loading scripts and I think this solution is acceptable medium-term, but
~ longterm we should fix our firmware loading scripts.

Koen
