Re: Service CPUspeed errors

The driver only depends on what processor u have. Most probably yours is P4M, so that would be speedstep_ich. You can try it by insmod speedstep_ich and see if it loads without errors.

There are others for less mainstream platforms.

Here's a list that I was able to come up with based on docs (may not be entirely accurate):
speedstep-ich (good choice for most mobile pentium 2/3/4 notebooks with the ICH2, ICH3, or ICH4 southbridge)
speedstep-centrino (better for centrino based systems, incorporates enhanced speedstep)
powernow-k6 (Older mobile K6-2 or mobile K6-3 cpu's)
powernow-k7 (Mobile Athlon)
powernow-k8 (Mobile Opteron or Athlon 64)
p4-clockmod (P4/Xeon processors, but doesn't provide voltage scaling, try speedstep-ich, or speedstep-centrino if possible and compatible)
elanfreq (Elan CPU support)
longhaul (Via Samuel/CyrixIII, Samuel/C3, Ezra, or Ezra-T CPU's)
speedstep-smi (Mobile P3 and P3-M with 440BX/XZ/MX Southbridge)
speedstep-piix4 (some systems, P3, P3-M, and P4-M with PIIX based southbridge)
longrun (Transmeta support)
gx-suspmod (National Semiconducter Geode or Cyrius Media GX CPU support for suspend modulation)

This info was gleened from the kernel config helper file and the CPUFreq docs.

Power PC (ibook2 and Powerbook), sparc64, and SuperH platforms are also supported.
