It may be worth trying to make it work with ivec4() instead of uvec4(). Ironlake is perhaps a little special in that it does have true integer support, but not GLSL 1.30.
Do you think it will be portable when converting special values from signed integers? As I read the specs, converting NaN with (u)intBitsToFloat() is already undefined, but seems to work. Won't representing specials through signed integers be leaving more room for different behaviour on various cards, drivers and GLSL versions? I can sure make it and test on what I have here, but it seems hard to be sure how universally this will work.
