That is already happening for old games, and while they usually run on simpler CPUs than modern ones, I don't see why this couldn't be possible for binary Linux drivers.

The toolchain would also be easier to match, unless they were using some proprietary compiler you can't get your hands on.

Just lookup how they match the toolchain, and find an agent harness to do decompilation.

I wonder if doing this kind of stuff with more recent software will cause more legal problems though. I am not really sure of the legal status of the resulting code.
