I had to borrow the magic constants from netbsd to get my m770 working.
Below is a patch against -current that works for m770 as found in
Thinkpad T43p. With that patch I get:

OpenBSD 3.9-beta (GENERIC) #5: Mon Feb 27 00:40:25 PST 2006
    gnezdonoog.nest.cx:/sys/arch/i386/compile/GENERIC
cpu0: Intel(R) Pentium(R) M processor 2.13GHz ("GenuineIntel" 686-class) 2.13 GHz
cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,CFLUSH,ACPI,MMX,FXSR,SSE,SSE2,SS,TM,SBF,EST,TM2
cpu0: Enhanced SpeedStep 1600 MHz (1356 mV): speeds: 2130, 1800, 1600, 1400, 1200, 1000, 800, 600 MHz

Changing hw.setperf works too, openssl speed about doubles when I switch between
hw.setperf=1 and 100. What do these values mean anyway?
