Besides what Brian just pointed out, it's also worth noting that the one 
problem that everyone dreads is creating LLVM code-generator for TGSI. 
Everyone seems to agree that it's a darn complicated task with a somewhat 
undefined scope. It's obviously something that will be mandatory for OpenCL, 
but I doubt anyone will touch it before it's an absolute must.
