Is there a platform where the amount of work to do for drivers is manageable for a from scratch linux replacement ? (And distro could then pick between the rinux or the linux kernel on that platform, and then extend the work to other modern platforms one at a time)

Or are there a lot of drivers that can be used on most platforms, and that would need to get RIIR before such a kernel could replace linux ?
