Perhaps not as unusual as reporting garbage, my CPU (AMD Athlon XP
2400+) claims to be "Unknown CPU Type". E.g. mprime chokes on this and
detects it as Cyrix... Could this be fixed by a BIOS upgrade?


CPU: Unknown CPU Type (2008.53-MHz 686-class CPU)
  Origin = "AuthenticAMD"  Id = 0x681  Stepping = 1
  Features=0x383fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CM
OV,PAT,PSE36,MMX,FXSR,SSE>
  AMD Features=0xc0400000<AMIE,DSP,3DNow!>
