Just to clarify a bit, my patch only uses the 800MHz hardcoded, which should work on all AMD64 processors. The max value used is the current running value.
No, it won't. It will fail on the new/upcomming CPUs with 1Ghz HyperTransport. The minimum frequency cannot be lower than the HyperTransport speed.
And for others sometimes laptop batteries are not designed to support more than 800Mhz.
Overall hardcoding such tables is imho a bad idea, unless you *really* know what you're doing.

OK, that's good to know.

Yes, sounds like it's not needed any longer. The ACPI tables seem to work fine.
