Hmm.. I have not had this problem at all. Originally installed SuSE
9.3, then did a partial upgrade to OpenSUSE 10 RC1. Then re-installed
with SuSE 10 when that came out. All were 64-bit versions. I had
major CPU fequency problems with SuSE 9.3, never this problem with the
keymap.

The BIOS have some MS compiled stuff in it that causes ACPI problems.
There is a way of fixing it by fixing the errors and recompile it.
I have not had time to do that yet.
But my CPU frequency scaling work perfectly. It ranges between 800MHz
and 1800 MHz.
Normally sits at 800 and then when I run some CPU-hogging app, it will
shoot up to about 1200 and then 1800, but will come down soon again.
The temperature stayes around 40 deg. The fan very seldom comes on.
If it does, (at around 75 deg) it soon cools the machine down to the
60's and shuts off again.
But that is rarely required.

I would also be interested in some docs.
THis is all I found up to now:
