Various CPU features aren't intel specific
|Assignee:||Hans Rosenfeld||% Done:|
There are a number of CPU features which, in cpuid.c are conditional on Intel being the processor vendor. Several of these (XSAVE/OSXSAVE/AVX and I think SSE3, SSE4, etc.) are actually now present on AMD processors and should be made generic.

perhaps you mean SSSE3, SSE4.x and co (judging by your patch)...
integration of this would be greatly appreciated!
