Here are the variables defined by NT 4 for a K6:

PROCESSOR_IDENTIFIER=x86 Family 5 Model 7 Stepping 0, AuthenticAMD

The PROCESSOR_LEVEL seems to be enough to report i586 and similar stuff. I
think that's much more safe. I don't have values for other processors here,
but the PROCESSOR_IDENTIFIER is obviously the result of cpuid instruction.
It also enable users to overwrite the detection.
