I appear to have run in to this bug (I have an old AMD Duron), as detailed in
another bug report:
https://bugs.freedesktop.org/show_bug.cgi?id=12398#c6

The debian bug report mentions a fix:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=442829#59

The fix seems to be a workaround.  They seem to have removed the -msse CFLAG,
as can be seen here:
http://ftp.debian.org/debian/pool/main/p/pixman/pixman_0.9.5-2.diff.gz

My impression is that it is desired that MMX and SSE should be supported
*separately*.  For Gentoo users, it is obviously desirable that libpixman (AKA
x11-libs/pixman-0.9.5) should respect the -mmmx and -msse CFLAGS.  I hacked the
build system so that I could build a working xserver.  Properly fixing the
makefiles is beyond me though.  I have filed a Gentoo bug:
