750 Ti fails with cuModuleLoad() 301 and cuMemAlloc() 1 errors

[Bilbo_Fraggins]

Using a Geforce 750 Ti on ubuntu 14.04 x64, with CUDA 6.0-37 and Nvidia 334.21.

cudaExample0.sh fails with cuModuleLoad() 301:

----------------------------------------
cudaExample400.sh and most other hash types I've tried fail with cuMemAlloc() 1

The cuda demos from the 6.0 install run fine, I assume I'm just hitting early compatibility bugs with the new versions of everything.

Any advice?
