I'm no mentor and thus don't take my comment too seriously, but I've 
started to work with CUDA recently (and may be doing so for my 
Bachelor's thesis) and would *love* to see some gcc support in this 
direction!

Regarding your points, I tend to favour point 1.  Thinking about it, 
when adding support for Co-Arrays to the Fortran front-end, maybe we 
could allow NVIDIA cards as backend for Co-Array'ed programs?  In 
general, it could be interesting to allow, for instance, writing kernels 
in Fortran, so existing code could be reused (or for the ones that like 
Fortran :D).  Maybe some basic support for that could be achieved, too? 
 (That is, gcc compiled kernels in some way.)

Yours,
Daniel
