Yep, that's quite believable.  See

  http://lwn.net/Articles/449448/ and especially
  http://lwn.net/Articles/449648/

for context.  Ugly stuff.

Now _ideally_ disabling aspm wouldn't cause the wireless driver to
hang.  So alas I think there's still more to fix around here.

Cc-ing mjg and the linux-pci list in case they have hints[1].

Thanks,
Jonathan
