Well AMD says it should run at 1.1V at that cpu speed. Of course that
means a 1.1V steady reliable power source, not one fluctuating between
1.0 and 1.2 (although Asus tends to have rather good power convertors on
their boards, although they still need a decent 12V feed).

You shouldn't need to mess with the voltages. They should be provided
by the bios and cpu.
I have tried acpi-cpufreq and that seemed to work on an athlon64 mobile
3200+ at least. Seemed perfectly stable to me.

Just make sure you don't let the cpu overheat.
