fbdev is (more or less) maintained, but it's a deprecated framework. All new Linux display drivers should be done on DRM.
What about no-mmu platforms? DRM has a big fat MMU dependency in the kconfig, is there a way to write DRM driver for such devices?
That would indeed be a showstopper...
I dropped the dependency, and gave it a quick try for m68knommu. Seems like DRM currently needs pgprot_writecombine() and pte_wrprotect(). Probably that can be fixed easily.
