(Get the code!)
Andy,
Thanks for putting this together. I've given it a go and the results are not as good as others, although better than the vanilla kernel.
On my system I lose the sound initially on boot, and in particular the inbuilt SPDIF is non-functional to start with despite selecting Digital output on the sound preferences. Instead I get a series of clicks from the machine and a bunch of messages in dmesg

This is a regression.
On the wireless side the driver is somewhat more stable than orginal. Unfortunately the rate selection algorithm leaves a little to be desired as it is selecting and sticking with rates that are not sustainable. I regularly lose IP throughput to the router despite the wireless showing as connected. When it stick like this and I force a reattachment I get the DMA stall message in the kernel log.

Sometimes I can do a remove and reinsert of the module, but it rarely brings the network back.
Mostly I get the usual message

This is on karmic.
