Enhanced speedstep diff for i386

Please test the diff at the following URL it add support for  
retrieving the frequencies and magic values for all the operating  
points from ACPI. You should test this if your machine comes up as  
'unknown enhanced speedstep' during boot.

The diff is here:
http://www.cs.ualberta.ca/~gklok/est.diff

This diff depends on ACPI please make sure that if you test that you  
disable APM.

I would appreciate tremendously that if you do test that you send me  
the dmesg, and
run

md5 -t at hw.setperf=100
md5 -t at hw.setperf=0
(make sure apmd isnt running when you test this...)

Thanks,
gwk
