- GPU driver improvements (they've already been working with nvidia, amd, and intel) which everyone benefits from
- kernel patches (maybe they fiddle with the scheduler or something) which anyone could pick up
- new/improved subsystems (perhaps they do some low latency input or audio layer), which (assuming they open source it) distros could choose to adopt or not
- improving porting techniques for bringing games or game middleware to Linux based platforms (everyone benefits)
It's possible that some stuff could be foreign enough to the way it has always been done on linux that it may take some time to make it upstream (see wakelocks from Android finally turning up in the kernel under a different name and a different implementation but providing the same functionality), but if it actually improves things, eventually I suspect the mainline kernel or distros or whomever will come around.
