I had the same problem on a MSI s260 (Medion version). Loading the
modules speedstep-centrino instead of acpi-cpufreq solved it for me.
Without being too much into it, I could imagine it hase something to do
with this patch: http://lwn.net/Articles/170568/

Especially the last part is interesting: "For Linux it means that on
systems which could run either the acpi-cpufreq or speedstep-centrino
drivers, only the (preferred) speedstep-centrino driver will load and
acpi-cpufreq will not load.  The possible side-effect is if somebody
configures only the non-preferred acpi-cpufreq, it will not load."

I hope this helps.

Apart from that: thanks a lot to the kernel maintainers that they got
2.6.16 so fast in debian! Great!
