No. You are assuming that bugs are intel-only and that other processors can not have same bug. For example 'wp bug' is shared over all 386's... And 386 popad bug was shared between intel and amd, also. So do not make cpuinfo specific to cpu type: apps do not want to know which cpus cannot have bug etc.
[Imagine application that depended on some behaviour of F00F. That application certainly would want to know how F00F behaves. If your approach was used, application would have to list names of cpu's that can't have bug and check against that ones...]
And - we do not want _another_ screen with bug-detection capabilities!

This is hard to do on 386's and such, and probably not worth effort.
