On i386 platforms at least, ACPI throttling is accomplished by the chipset
modulating the STPCLK# pin based on the duty cycle. Since p4tcc uses the
same mechanism (but internal to the CPU), we triggered a hang on some
systems at low frequencies when both were in use. Now, disable
acpi_throttle when p4tcc is also present.
