I updated the BIOS on my Fujitsu-Siemens Amilo M1425 to BIOS version 1.08 (released December 2004, only two weeks after my previous, buggy BIOS, ver 1.06c).

With the new BIOS, acpi-cpufreq now loads successfully, detects the clock speeds available, and scales the cpu frequency correctly. This is on Gutsy kernel 2.6.22-7.

Windows also no longer needs the assistance of the third party freq scaling app, Notebook Hardware Control. Looks like it was buggy ACPI all along.
