What I did:

Edit /etc/cpuspeed.conf, modify the DRIVER line to read:
DRIVER="speedstep-smi"

Add module parameters to /etc/modprobe.conf:
#enable speedstep for PIII on 440BX
options speedstep-smi smi_port=0xb2 smi_cmd=0x82 smi_sig=1

The cpuspeed daemon should now start on each reboot and vary processor
speed depending on load.  My cpu/MB combo supports 1GHz/700MHz.  You can
verify current speed with cat /proc/cpuinfo.

This laptop identifies itself as: Winbook Z1, BIOS 1.06A.
