+- Use pixmanFillsse2 and pixmanBltsse2
+
+- Be consistent about calling sse2 sse2
+
+- Rename "SSE" to "MMX_EXTENSIONS". (Deleted mmx extensions).
+
+- Commented-out uses of fbCompositeCopyAreasse2()
+
+- Consider whether calling regions region16 is really such a great
+ idea. Vlad wants 32 bit regions for Cairo. This will break X server
+ ABI, but should otherwise be mostly harmless, though a
+ pixman_region_get_boxes16() may be useful.
+
+- Altivec signal issue (Company has fix, there is also a patch by
+ dwmw2 in rawhide).
+
+- Behdad's MMX issue - see list
+
+- SSE2 issues:
+ - Crashes in Mozilla because of unaligned stack. Possible fixes
+ - Make use of gcc 4.2 feature to align the stack
+ - Write some sort of trampoline that aligns the stack
+ before calling SSE functions.
