I think there is a problem with your assembler, but I am
not enough of an assembler guru to say what.

This works for me with gcc 3.0.2 and binutils 2.10.91.0.2-3:

__asm__("movq %mm2,%mm0"); 


I recommend you look at the tutorials on:
http://www.linuxassembly.org

And also the binutils mailing list:
