I'm sure it would be possibel to save a lot of text size. But I don't think removing the relatively small CPUID code is the right way. That is just a big maintenance issue for little gain.
If you're seriously interested you should start measuring and then attack the real bloat pigs. e.g. a good way is to look for unneeded inlining.
And also do regression testing, like running bloat-o-meter between releases and complaining about subsystems which have grown unduly.
