Public bug reported:
After upgrading from Edgy to Feisty, CPU frequency scaling stopped
working. It seems that Edgy was using speedstep-centrino.ko. speedstep-
centrino.ko was removed and acpi-cpufreq is supposed to be used instead,
but in my laptop acpi-cpufreq reports just:
[EMAIL PROTECTED]:~$ sudo modprobe acpi-cpufreq
FATAL: Error inserting acpi_cpufreq
(/lib/modules/2.6.20-9-386/kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko):
No such device
Please restore speedstep-centrino.ko as a fallback.
