OK, after some further investigating here's what happens. The ACPI table
parsing is there, and works. I was just updating my patch to 2.6.6, and 
did not pay much attention to what else had changed.

However, since my computer locks up as of 2.6.6 if ACPI processor is
compiled in, I've had it compiled as a module. Loading it after the init is
done does not lock up the system...

So I had CONFIG_ACPI_PROCESSOR=m, and that made the powernow-k8 ACPI
detection to fail. It now works good with the following little patch. Now
I also have the 1600MHz in addition to 800MHz and 1800MHz :)

I can keep my earlier patch around on my website in case somebody needs it.
It could also be included as secondary fallback if both ACPI and BIOS fail.

What happens with the ACPI speed tables with CPU upgrade BTW? Are they
hardcoded, or generated by the BIOS?
