Thank you very much for the complete report. Everything that I needed to diagnose your situation was included. The problem is not that the driver is failing to report the association, but that the driver cannot associate when the signal/noise is as low as you have. You have only 6 dBm difference in the received strength. Due to residual bugs in the PHY and radio setup, the transmitted signal/noise is even lower. To associate and authenticate, you need a stronger signal. There have been a number of changes that influence the transmitter strength since the 2.6.20 code was frozen. If you are willing to rebuild your kernel, try the fixes contained in ftp://lwfinger.dynalias.org/patches/combined_2.6.20.patch. Those may help you. The only other "fix" I can offer is to reduce the attenuation between your AP and the computer by moving closer.
