As Dominik was missing and there was no action on the linux-pcmcia
list, I took advantage of the fact that this is a wireless device and
submitted the patch to John Linville. It is commit
e4a01604b8e5656f3a059f52b3e8f2560740c057 in the wireless-testing tree
and was sent to DaveM on July 24 for linux-next. It will be in 2.6.32.
