What's wrong are the "cpu family", "cpuid level", and the "flags."

Yep.  On my 2.0 kernel, the CPUID and flags are detected correctly:

    cpuid level     : 1
    wp              : yes
    flags           : fpu de tsc msr cx8 cmov mmx

Why aren't any of these flags detected in the 2.1 kernel?  Why does 2.1
think that a 6x86 is a cpu family of 4?  I don't get it

More importantly, why does the CPU type detected change if you set SMP=1?
