Mine says AMIBIOS 08.00.09, Build Date 02/09/04. Don't know why that
looks totally different from yours. I've found it in a submenu under
"Advanced Configuration" in the BIOS setup screen IIRC.
You need to enable ACPI, else the cpufreq directory
(/sys/system/cpu/cpu0/cpufreq/) stays empty. I'm using
"acpi_sleep=s3_bios" in my kernel command line. I've never tried
other values, however (and suspend doesn't work).

I can control the cpu fan only (which is the loudest anyway). I'm
doing that with a small user space script. While the cpu isn't busy,
the fan stays off most of the time (below 33°C) and runs on lowest
speed the remaining time.
