It's in Intel's next generation ia32 chips, currently code-named
Willamete (sp).  The primary extensions are 2 vector doubles
(instead of 4 vector floats), as well as more integer manipulation.

AFAIK, there are no current plans for implementing SSE2; but it
doesn't sound very hard at all, once Red Hat's current SSE code
is integrated.
