BTW, are you sure throttling work OK?
In order to test this, you may try something like 'openssl speed md5' for
each levels.  The results given should be roughly linear.

Also I'm wondering what is actually the output of ACPI tables.  Would
help if you do something like that:

wget ftp://ftp.kernel.org//pub/linux/kernel/people/lenb/acpi/utils/pmtools-20031210.tar.bz2
tar xjvfp pmtools-20031210.tar.bz2
cd pmtools-20031210/acpidmp
make
sudo ./acpidmp > acpidmp.out
bzip2 acpidmp.out 

Then mail me the acpidmp.out.bz2

I'm in fact more interrested with FADT and DSDT, but other tables
wont hurt.

I'm still wondering if I'm right to think that its not an intel
chipset.  If its an Intel one, then something is wrong.  Intel chipset
support 8 throttling levels, not 16.  Could you please do a lspci -v?
