I can't recall where in the code this is, but it is the bios which provides the voltage/frequency pairings. The speed-step drivers for older processors actually have them hard-coded as a table. If you're not seeing the highest frequency - I don't know what the problem is. Mine re-appeared after the rmmod psmouse trick I posted earlier. The CPU specs are in a separate SSDT on my laptop, which only shows up when the appropriate bios setting for speedstep is ticked, and the bios is "happy" (psmouse removed before shutdown).
