i think instead of changing 'ht' to 'ht_detect', it would be even more intuitive to only expose the 'ht' flag if the ht-detect capability is there _and_ if the number of siblings is 2 or more.
That way we dont change it - we just 'hide' the 'ht' string on the category of systems that can enumerate HT via the CPUID but dont actually have HyperThreading.
Hm?
