Good suggestion Andreas. I've found the problem.
It slipped my earlier observations that whenever i ran the SDK
deviceQueryDrv, the clock rate was always displaying as "0.0 Ghz" and it
didn't occur to me that my Mac Book Pro (has 2 GeForce cards - 9400m and
9600m) was choosing the 9400m low powered chip and for some reason the 9400m
device wasn't returning properly but i dont know enough to know why this is
Is this a bug with nvidia or with mac os x? I don't know

Try inserting the query right after PyCUDA's call to cuInit (see
src/cpp/cuda.hpp, l. 316 or thereabouts--look for cuInit). If it fails
too, then it's likely an Apple or Nvidia bug.
