Took me a little bit to figure it out, but the module is built and 
loading.  But, it doesn't provide anything useful.  In fact, it doesn't 
provide anything at all.  :(

A kernel with CPU_ENABLE_TCC provides me with the hw.p4tcc sysctls that 
I can use to change the CPU frequency.

A kernel without CPU_ENABLE_TCC doesn't give me any throttling / 
frequency settings.  Loading the cpufreq.ko module doesn't change 
anything.

This is on a Toshiba Satellite A60, bios 1.80c.  It's a 2.8 GHz Celeron 
(P4).  It's not the greatest BIOS or ACPI implementation.  :(
