Okay, I tried again with 2.6.25-rc8 from linux-2.6 git. Speed is still 
great. However, with both wireless-testing and linux-2.6 I seem to be 
using the 'pid' algorithm:

phy0: Selected rate control algorithm 'pid'

With 2.6.24 I seem to be using the 'simple' rate control algorithm. I 
don't know how to switch rate control algorithms without rebuilding 
though, so I can't test 'simple' with 2.6.25.
