That should work after upgrading linux if the Intel GPU is enabled (see 
http://nouveau.freedesktop.org/wiki/Optimus/ for how to check that), but 
shared local memory won't work.  (There is a fix for that, but for 
security reasons I can't recommend it:

I agree: one of my goals is to have OpenCL just work (without the user 
needing to specifically set it up), which requires proper "hardware not 
supported" handling:

That was supposed to be fixed (#721103), but #767985 suggests you're not 
the only one with that problem.

Oblomov as in the author of this clinfo?  We're currently discussing 
whether to replace Debian's clinfo with it (though due to the release 
freeze, this can't happen immediately):
