Hello Craig,

I have a little objection to this patch. We need a way of
disabling SSE/SSE2 instructions. I have seen a lot of performance lose on VMWare 3.2 and also 4, which apparently, is
supposed to emulate SSE instructions better, but it doesn't. :)


	If we can do it like 5.x, and add a CPU_DISABLE_SSE option, it
	will be much better, IMHO. :-)

Cheers.
