I had the same effect when trying to update from 2.6.15 to 2.6.17. Do
you have acpi compiled in (instead of as a module) or do you load the
acpi module before speedstep_centrino? It seems that acpi tries to load
acpi_cpufreq, which used to work here but since 2.6.17 doesn't anymore
and leaves the frequency scaling in a busy state. It should be fixed in
2.6.19, although I haven't tried.

If the above seems to correspond to your problem, try compiling all of
acpi as modules and to load speedstep_centrino first.

Anyway, quite a long shot in the dark.
