I included some more information about my system in my first mail, but anyway.
the IMHO relevant dmesg messages are:
Machine check exception polling timer started.
powernow: AMD K7 CPU detected.
powernow: PowerNOW! Technology present. Can scale: frequency and voltage.
powernow: Found PSB header at c00f17f0
powernow: Table version: 0x12
powernow: Flags: 0x0 (Mobile voltage regulator)
powernow: Settling Time: 100 microseconds.
powernow: Has 14 PST tables. (Only dumping ones relevant to this CPU).
Enabling SEP on CPU 0
I did a little bit of investigation in the kernel source (powernow-k7.c) and
downloaded x86info. The Output of x86info --pm --bios with the following
clueless little patch.

So it seems to me that the BIOS doesn't have the tables for my Athlon
model/stepping. I tried to get a new bios from hp, but it didn't change anything
relevant (they changed something in the PSTs but did not add a new one for my
processor)

I think it would be a good thing to display a Message explaining why powernow
isn't working to the user in the case that no relevant PST is found.
Can you suggest any workaround for this problem, or is my only option to
complain to HP do supply an updated BIOS.
I very much would like to have a way to override (or add to) the bios provided
values. BTW windows XP somehow manages to use powernow on this laptop anyway.
