According to AMD docs (#20734, rev. i), the K6 (6.2) should return
0080_01BF on CPUID1 in EDX, which means
fpu, vme, de, pse, tsc, msr, mce, cx8, mmx

Later versions of the K6 (7.1) add "sep" and "3dnow" (8.0 = K6-2).

Bit "10" is not documented in the above doc!
It's correct for the kernel to report it like that then ...
