MMX for memcpy?

Hi

I realized some varieties of Pentium can memcpy fater by loading
MMX registers and then unloading them. Is it meaningful to use this
for optimizing memcpy actions used by kernel? Could SSE help on processors
which support SSE?

Where is the memcpy in kernel placed? In kernel sources, or in libc?
