Description Victor Balada Diaz 2006-02-24 12:20:03 UTC
	cpufreq just detects frequecies up to 1500 mhz, but this CPU have
	a frequency up to 2000 mhz.

State Changed
From-To: open->analyzed

The Enhanced SpeedStep driver was written before Intel released mobile 
processors with a 533MHz bus speed; it is recognizing the processor as 
having a 15x clock multiplier, and deciding that this means it is a 1.5GHz 

This means that the Enhanced SpeedStep code has incorrectly recognized the 
processor and there may be frequencies which the driver is unable to use; 
but the main effect is simply that the frequencies are printed incorrectly: 
The frequency 2.0GHz is reported as 1.5GHz, the frequency 800MHz is reported 
as 600MHz, etc. 

Until this can be fixed properly, I suggest ignoring the frequency information 
returned by the driver; if the submitter uses powerd(8) he will find that it 
operates just as well in spite of the driver being somewhat confused.
