Check current git. I've moved SourceModule and its related infrastructure to 
pycuda.compiler. Now you can get the cubin that results from compilation by 
calling pycuda.compiler.compile with the same arguments as SourceModule. You 
can then do with it whatever you want. There's also 
pycuda.compiler.compile_plain() that skips a bunch of niceties that compile() 
has, such as caching, compute model detection, etc.

PS: Don't worry, everybody else. SourceModule in pycuda.driver still exists--
it will print a (silenceable) deprecation warning once per Python interpreter 
invocation, though.
