The penguins have developed a "stable" userspace driver API to allow "most" of a driver to be in userland. http://liquidat.wordpress.com/2007/07/21/linux-kernel-2623-to-have-stable-userspace-driver-api/ No DMA (yet?). Not for drivers requiring the highest possible performance. It doesn't solve the problems of binary-only drivers. (security, fixing bugs, CPU arch, ...) But if they did a reasonable job (and yes that's a significant if), it might be useful for many drivers. Perhaps a way to share drivers between Linux, the BSDs, OS-X, OpenSolaris, ... Thoughts?
