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.
