Yea. When I first looked at PTX, my thought was to use the existing 
testsuite, to the extent possible, to shake out the initial code 
generation issues.  There's just some things that would require heroic 
effort to make work and they aren't really a priority for PTX.

So I've got not problem conceptually with the direction this work is taking.
