isn't there something low-level, driving the CPU/chipset registers directly
?
Like... The BIOS? :)
Seriously, the acpi-cpufreq driver needs good data from the BIOS's ACPI tables
to be able to do anything. Try booting with 'cpufreq.debug=7' added to your
kernel boot params, and you should get some more data on why its failing to
work, but pretty sure its the BIOS at fault.
