...this sux, I can't get it to work:  I can't understand why we'd  
want more than one check for cpu type?  Is it likely that a process  
will init and start running on one cpu, then switch to a different  
type (not talking about core-duo's here)?  I don't think so...

...also, are you expecting the static declaration of m_simd in  
GemPixUtil.cpp to actually work, because it doesn't on OSX:  why not  
have a GemMan global variable, then refer to it via GemMan::m_simd?

...without hearing your thoughts behind it, I have to abandon my work  
on the color conversion routines...come to think of it, nothing has  
been quite right this whole day...
