Distribution:
RH + 2.6.0-test8

ASUS M2400

Problem Description:
In this laptop, _PPC return 4, and _PSS return 10 states record, and only 8
states are accepted due to current limitation of ACPI_PROCESSOR_MAX_PERFORMANCE
which is 8. current_state didn't get properly initialized. And ACPI CPUFreq
driver doesn't work as expected.
