Hi SÃ¸ren,

This looks like a great patch, but I'm wondering, why not change things so
there's an fb_asm.c (or whatever) which appropriately #includes another source
file with the MMX code? This would make things cleaner for other people who want
to do the same thing for other platforms (PowerPC's Altivec, IA64's multimedia
instructions etc).

On that note, I think the potential speed gains for text rendering will be even
more significant on these other platforms, since GCC does a worse job there, and
vendor-accelerated RENDER extensions (e.g. NVIDIA's) are nowhere to be seen.
