Thanks for taking a look at this. So well, it would be a
misconfiguration bug by the distribution then to try to support a
generic 686 kernel wihtout GENERIC then.

Well, it may be intentional -- some distros simply exclude support for the lower-volume VIA processors, since that might imply building their "generic 686 kernel" sans CMOV and some other instructions, and changing the compiler's instruction scheduling to something less optimal for the majority. :/


X86_GENERIC shouldn't disable CMOV?

We're only referring specifically to the family == 6 VIA processors here.
