In general I'd expect this to be rather unlikely, but I guess much
would depend on the actual reasoning done in the description.

Which functionality? So far you've talked of only CPUID bits I
think, without explaining at all what functionality you want to
have that depends on these. In general, as said earlier, CPU
management is the hypervisor's responsibility, so I'd rather
not see this virtualized, but the hypervisor be put into a
position of doing whatever is needed.
