I use speedstep-centrino with it, and after boot all is usually okay.
But after a few hours of operation, it stops shifting to the highest frequency
even under continuous 100% load (or not). Eventually it gets stuck at 600Mhz
and stays there until I reboot.

cpufreq seems to have relatively frequent problems.

And how can I fix it?

You could start by telling us which kernel versions are affected ;)

Heh. and 2.6.18-rc3-git4 are the two kernels I have for it,
and both exhibit the problem.

boot with cpufreq.debug=7, and capture dmesg output after it fails

I'll reboot with the debug options and see..
