500Mhz reported as 133Mhz w\ dmesg

[Stephen L Martin]

Hello,

I have a IBM ThinkPad 600X. 500Mhz Pentium III, 128MB RAM.
Machine type is 2645-4EU

http://www-3.ibm.com/pc/support/site.wss/quickPath.do?quickPathEntry=2645-4EU&quickPathEntry.x=5&quickPathEntry.y=7

When I do a dmesg it reports:

CPU: Intel Pentium III (135.87-MHz 686-class CPU)
  Origin = "GenuineIntel" Id = 0x681 Stepping = 1
  Features=0x383f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,
MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,SSE>

I have tried recompiling the kernel with only I686 to no avail.

Thanks,

Stephen
