Re: [ACPI-sppt] <not supported> for /proc/acpi/processor/CPU0/performance

Guys, this simply means that the CPU/Chipset DOES NOT support ACPI based
frequencey/voltage scaling. For transmeta Crusoe based laptops you need
to enable the longrun stuff in the CPU Frequency Scaling section in the
kernel config, and then use a user-land nutility to manage performance.
