GPU's as floating point coprocessors

Ok.  I didn't get that far in watching the channel 9 video.  So it 
sounds like OpenMP for the GPU then.  Neat.  How's the support for 
double precision floating point?  Also what happens when the user has 
crappy built-in Intel chipset graphics?  If they're going to solve those 
issues for us then it will be very useful indeed.
