Comment 28 for bug 231534

The Acer Aspire 3000WLCi doesn't seem to come with a Turion ML37, but with a Sempron. Perhaps that's why your BIOS doesn't support it properly? What BIOS version are you using, version "3A32"? Perhaps you can try the "Vista" BIOS as well.

Either PSB or _PSS is required to be present in your BIOS information for Linux frequency scaling to work (if it isn't defined in another way). I just meant that Windows 2000 won't work either if neither are present in your BIOS (ACPI) information.

The Aspire 30xx and Aspire 50xx indeed seem to be alike (and I know for certain 302x and 502x are in fact identical) and there may be a Ferrari notebook that is identical as well, except for its casing. However, I wouldn't know which one is. But the Ferrari's are better and longer supported.

At tuxmobile.org no-one mentions any difficulty with the frequency-scaling of this notebook. Have you tried other Linux distributions/live-CD's? I suspect the Turion is just not supported by the BIOS.
