I've my 2.31 kernel running (from archlinux repositories) and
compat-wireless 2009-11-06 and now not even with pid i get it working
good. It goes to the max rate available.

11Mbps

I'll compile wireless testing and i'll post the statistics, or if
someone tell the information they need to debug it i'll post it.
