I think that if I use SSE optimalization for GCC it would take care about it but the root of evil is in assebler files that are out of gcc control. If I disable HAVE_MMX in config but leave sse opts in makefile it works. It probably only not use assembler routines but still may use sse for other C-code. I didn't checked listing but binary is different size when use sse and when use mmx.

If I would want to use SSE in my code and need to have aligned memory I think it could be possible to use valloc() that should allocate page-aligned blocks of memory...
