Just so we're all on the same page, the project's short term focus is 
getting Clang support into mainline (now that clang is mostly fixed), 
and then working on things like enabling IA in the Linux kernel code.

Pax Team has done some great work to enable IA, but smaller, simpler 
steps are needed right now. Once in mainline there will doubtless be 
more people interesting in helping to fix these sort of things.
