People,


	I dont know if its the case, but I have a K6-2/500 but my FreeBSD
4.1.1-STABLE detects only 475:

----------
Timecounter "i8254"  frequency 1193182 Hz
CPU: AMD-K6(tm) 3D processor (475.29-MHz 586-class CPU)
  Origin = "AuthenticAMD"  Id = 0x58c  Stepping = 12
  Features=0x8021bf<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8,PGE,MMX>
  AMD Features=0x80000800<SYSCALL,3DNow!>
----------

	The same machine when I was in 3.5-STABLE:

----------
Timecounter "i8254"  frequency 1193182 Hz
CPU: AMD-K6(tm) 3D processor (501.14-MHz 586-class CPU)
  Origin = "AuthenticAMD"  Id = 0x58c  Stepping = 12
  Features=0x8021bf<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8,PGE,MMX>
  AMD Features=0x80000800<SYSCALL,3DNow!>
----------

	Should I try these options or this is a normal behavior?
