est.c:
* Use a quintuplet (vendor, MHz_hi, mV_hi, MHz_lo, mV_lo } to match
CPUs more correctly than parsing the brand string.
* Add support for a bunch of models.
* Create a fake table on the fly if the CPU is unknown (there's no
table for it) with the current/highest/lowest frequency.
specialreg.h:
* Add some MSRs needed to get the bus clock value.
identcpu.c:
* Add functions specific to Pentium III, Pentium M and Pentium 4 to
get the bus clock value.
Note that the new fake table code from Simon Burge is not included on
this commit.
