Jeff asks:
>Is there any way to detect SSE?

Yup, it's bit 25 in EDX from CPUID with EAX = 1
add the variable and the line:
 has_SSE = and_bits(EDX, #02000000) != 0

MMX - yes
3DNow - maybe
SSE - unlikely, but if you can convince me to...

I have an AMD K6-2 3DNow at home which supports MMX and 3DNow, and an Intel
P3 Xeon at work which supports MMX and SSE.  Looks like I've got it covered,
now all I have to do is code the instructions into asm.e.
