You mean, SSE2 intrinsics, not general support for SSE2, which already
was in GCC 3.1, right? Or did I misread gcc-3.1/changes.html?
The compiler now supports MMX, 3DNow!, SSE, and SSE2
instructions. Options -mmmx, -m3dnow, -msse, and -msse2 will
enable the respective instruction sets. Intel C++ compatible
MMX/3DNow!/SSE intrinsics are implemented. SSE2 intrinsics
will be added in next major release.

As far as I remember your patches, many which were applied both to the 3.2
branch and mainline (IIRC), I'd say yes.
