freqency scaling on compaq nx9010

[Thomas Eschenbacher <Thomas.Eschenbacher-Mmb7MZpHnFY@public.gmane.org>]

Hi,

I have a compaq nx9010 laptop, running on kernel 2.4.9-gentoo-r13, with 
ACPI enabled and speedstep for frequency scaling. Speedstep itself works 
rather fine, but I wonder about the available scaling frequencies:

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
gives only "668000 692000" ?

...and this is also what speedstep does - it switches between these two 
frequencies, 96% and 100% speed. Isn't this absolutely nonsense? Only 4% 
speed difference !?

I now have fixed the bios' DSDT and built my own one in the kernel - no 
change. Furthermore I cannot find the numbers 668000, 692000, 668 and 
692, neither in decimal, nor in hex in the decompiled dsdt.

On the other hand my dsdt contains two entries in the _PSS section, one 
for 3059MHz (100%) and one for 1596MHz (~50%) - but those two 
frequencies appear nowhere in /proc or /sys/devices/... !?

what goes wrong here ?

Is speedstep independend from ACPI ?

Thomas
