I don't really understand...
I've tried the PREFETCH version on celeron-2 and it worked!
What's the difference between PREFETCH and PREFETCHNTA ?
(in viewpoint of both speed and supported CPUs)
AFAIK the mmx2 is called xmm in /proc/cpuinfo. AT least for cel2/p3 + kernel
2.4.3. Older kernels called it kni or sse.
Where is it called 'mmxext'?

Thank you for patches. Do you have account at SF? (Then I can add CVS write
access, simpler way to apply changes)
