Ok, thanks for the info.
I got better wi-fi throughput with nokia 2.6.21 kernel compared to
linux-omap kernels, but the CPU speed difference will most likely
explain that. I'm assuming that DVFS increased the CPU speed over 400
MHz when running throughtput tests on nokia 2.6.21 kernel.
If anyone have hints or pointers how to overclock linux-omap kernels,
I'm all ears :)
