Seems to work well on my rt61pci card!
In fact, it reports a higher link quality (and maintains a higher
bitrate) than the version in current wireless-testing. The quality
report also fluctuates less than previously. This is consistent over a
few hours of testing with streaming PCM audio.
I do get a lockdep warning when bringing up the device, however.
