I've got the newer revision:

CPU: VIA Eden Processor 1200MHz (1200.01-MHz 686-class CPU)
  Origin = "CentaurHauls"  Id = 0x6d0  Stepping = 0

Features=0xa7c9baff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,APIC,SEP,MTRR,PGE,CMOV,PAT,CLFLUSH,ACPI,MMX,FXSR,SSE,SSE2,TM,PBE>
  Features2=0x4181<SSE3,EST,TM2,xTPR>
  VIA Padlock Features=0xffcc<RNG,AES,AES-CTR,SHA1,SHA256,RSA>

That's actually why I had to move to 6-STABLE. The CPUID detection
routines for the 0x6d0 revision aren't in 6.3-RELEASE.
