OMG, I just spent about 6 hours figuring out how to get boinc GPU to work on my linux box. First there are about 50 ways to get the Nividia drivers install and only one of the 50 works. Then there is the problems with Boinc not detecting a usable GPU. Lots of ideas on this one. It comes down to Boinc being able to access the cuda drivers. The final fix was for me to set SELinux to permissive. Basically turning it off.
