On my ASUS K52Jc these controllers are also reported "disabled".  This
is after switching to Fedora 16 with its 3.1.2-1 kernel.

After doing these updates I had also to add "ath ath9k" to my list of
SUSPEND_MODULES (which are removed and reinserted in these operations)
or otherwise I will loose my wireless connection on a resume and a
reboot after hibernate will silently die.  In logs I can find

 irq 17: nobody cared (try booting with the "irqpoll" option)

 Disabling IRQ #17

These "irq 17: nobody cared" were happening before but I could get away
without touching ath and aht9k modules.
