Some guy wrote to Carmack and asked about a Linux version of Rage. Carmack responded:

OK, maybe not that interesting or surprising. It's still a big ouch to AMD.

The PC and Mac versions are still OpenGL 2.x.
We are not currently scheduling native linux ports. It isn't out of the
question, but I don't think we will be able to justify the work. If
there are hundreds of thousands of linux users playing Quake Live when
we are done with Rage, that would certainly influence our decision...

Yes, it is. The codebase is much, much larger, and the graphics
technology pushes a lot of paths that are not usually optimized. It
probably wouldn't be all that bad to get it running on the nvidia binary
drivers, but the chance of it working correctly and acceptably anywhere
else would be small. If you are restricted to it only working on the
closed source drivers, you might as well boot into windows and get the
fully tested and tuned experience...
