Update: on my second recompile (after adding the printks) it started
working. I'm not sure why it failed the first time.
However there is a huge performance regression. "tptest" shows a TCP
throughput of under 300 kbit for the driver version 2.0.9 (current
wireless-2.6), compared to 7 Mbit for version 2.0.7 (with kernel
2.6.23-rc3). The UDP speed was also affected but not as much, down from
around 5-10 Mbit to 1 Mbit.

With the printks below I get the following:
Oct 15 13:14:43 better kernel: selected mode 2
Oct 15 13:14:43 better kernel: selected channel 8
Thanks,
