How is that version constructed and iterated, or example is the
0x01000000 bit always set?
If it's always set then it might make sense to turn this into a more
human-readable version number: mask out the 0x01000000 and report
0xc4 as 194? Or is the *real* version above just '4'?
Should 0x010000c4 perhaps be printed as 1.10.4?

Well, if Intel does similar encodings as AMD, then it would be nice
to turn that into human-readable version strings as well.
Thanks,
Ingo
