Yes, you need two things:

- you might have to run OpenCL applications with 
LD_PRELOAD=/lib/ (when they're single thread applications 
like clinfo)
- you have to rebuild the kernel driver with this patch

keep in mind that Clover is not very good. It can't yet handle Blender, 
doesn't have image support for Darktable, etc.
