Is there anything I can to do to dissect this problem further? The
ipw2915 card is attached to a PCI-PCI bridge. I'm not sure if this
bridge is resumed from sleep correctly, the linux kernel knows nothing
about resuming this bridge and just restores the PCI config space,
which still ends up being different before and after resume. But maybe
I'm totally on the wrong track...
