Nick's fastmemcpy benchmark was moved to CVS, under TOOLS/
I've fixed 16-byte aliging problem for SSE, so it works on SSE too.

My results on celeron-2 600 overclocked to 900, 256MB PC133 ram:
./fastmem-k6:  Illegal instruction
./fastmem-k7:  v2-v1=55224677
./fastmem-mmx: v2-v1=58553622
./fastmem-sse: v2-v1=54496382

In MMX version the standrd glibc memcpy() was used.
(so it isn't really MMX code, except if glibc has MMX asm)

I think, with video memory these results differs a lot!
I'll make some tests with G400's memory as destination.
