Works for me:

fk@r500 ~ $dmesg | grep TSC
Calibrating TSC clock ... TSC clock: 1995045800 Hz
  Features=3D0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PG=
E,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>
  TSC: P-state invariant, performance statistics
TSC timecounter disabled: C3 enabled.
Timecounter "TSC" frequency 1995045800 Hz quality -1000

Thanks a lot.

Fabian
