There is a "PPM mode" option which has possible values: Native - Native mode is for fully support ACPI OS (ex. Win XP, Vista) SMM - SMM mode is for legacy OS (ex. Win 2k) Setting it to SMM didn't help. Gave the same error for acpi_cpufreq. Btw, you were right about FC trying all the module, but it apparently tried only speedstep modules for some reason. It's clear from my dmesg.txt that all the speedstep modules are attempted. Forgot one obvious thing when I ran dmesg -- forgot to run it after trying modprobe acpi_cpufreq. This is what I get when I do that: acpi-cpufreq: acpi_cpufreq_init acpi-cpufreq: acpi_cpufreq_early_init cpufreq-core: trying to register driver acpi-cpufreq cpufreq-core: adding CPU 0 acpi-cpufreq: acpi_cpufreq_cpu_init cpufreq-core: initialization failed cpufreq-core: adding CPU 1 acpi-cpufreq: acpi_cpufreq_cpu_init cpufreq-core: initialization failed cpufreq-core: adding CPU 2 acpi-cpufreq: acpi_cpufreq_cpu_init cpufreq-core: initialization failed cpufreq-core: adding CPU 3 acpi-cpufreq: acpi_cpufreq_cpu_init cpufreq-core: initialization failed cpufreq-core: no CPU initialized for driver acpi-cpufreq cpufreq-core: unregistering CPU 0 cpufreq-core: unregistering CPU 1 cpufreq-core: unregistering CPU 2 cpufreq-core: unregistering CPU 3 Attaching the files I sent to Zaho so others can look at it too.
