speedstep-centrino on Toshiba Portege M100 V1.50 doesn't work

[Henne]

Hi,

I've upgraded the BIOS of my Toshiba Portege M100 from V1.10 to V1.50.
Now "modprobe speedstep-centrino" and "modprobe acpi-cpufreq" leads to the same result.

FATAL: Error inserting acpi_cpufreq
(/lib/modules/2.6.22-3-686/kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko):
 No such device

dmesg says:
speedstep-centrino: couldn't enable Enhanced SpeedStep

I've tracked it down that bit 16 of MSR_IA32_MISC_ENABLE can't be set.

Under WindowsXP does it work. Somehow!

Do you know something I could try to enable it or how I may
find out how it now, after the update, works?

Greets,
Henne

P.S.: cat /proc/cpufreq
