This also fixes bus speed detection and makes speedstep work on my Thinkpad W500. There's a caveat though, you need to rm your old build dir first, otherwise the resulting kernel will page fault at boot. EST is still weird here, but this is probably fixable: cpu0: unknown Enhanced SpeedStep CPU, msr 0x0617492506004925 cpu0: using only highest and lowest power states cpu0: Enhanced SpeedStep 19467 MHz (1292 mV): speeds: 19467, 1600 MHz Thanks, Mitja
