Wonder what they use to detect CPU capabilities, because:
[EMAIL PROTECTED] bin]# objdump -d tier0*.so | grep cpuid
fde6: 0f a2 cpuid
fe06: 0f a2 cpuid
fe26: 0f a2 cpuid
fe46: 0f a2 cpuid
fe56: 0f a2 cpuid
fe66: 0f a2 cpuid
fe86: 0f a2 cpuid

fee1: 0f a2 cpuid

I wrote a few hacks to use movnti inst instead of whatever glibc/gcc
uses/compiles for memcpy, so I save L1 cache :)
