Well I'm an idiot. I was reading wrong documentation and didn't extract the icd-registration file to the right place. For anyone else as dumb as I am, with SDK 2.4 you need to do: $ sudo tar xzf icd-r...

I don't believe the VM guest will be able to access the GPU functions necessary. Why would you run it in a VM any way? There are both Windows and Linux versions. Are you on a Mac?

Backtrack is irritating. The only reliable way I've found to run OpenCL apps in Backtrack is to open an X session and run the OpenCL app from an Xterm window.
