> The Debian page about the powernowd says that it "does not depend on APM =
or ACPI". My question is: can I not use CPUFreq (and some deamon e.g. power=
nowd) when I'm running APM, or must I use ACPI?

I'm running powernowd with apm. You just need to have all the cpufreq
modules loaded (especially cpufreq_userspace (i'm not sure that it's the
correct name. It's hard compiled in my kernel (options
CPU_FREQ_GOV_USERSPACE)).
