Nice that you could test it.
The payload wasn't from me, just the link to it. (It's directly on the seabios 
homepage, kevin built it some time ago.)

Interesting, and good that you mention that!

When I tested the PowerNow! stuff, I also recognized that, but it seems that I 
flipped the results. My point of view was that coreboot offers one more stepping 
mode, and therefore didn't care about it.
Maybe Rudolf Marek can us help here, because he wrote the automatic generation 
for that ACPI table (SSDT).
