I highly doubt the nvidia binary driver would ever work on a NOMMU x86. I don't think they have any interest in supporting anything other than the 99.999% standard x86 setup. Running x86_64 without MMU simply sounds insane. I can't imagine there is a good reason for doing it. The memory fragmentation issues with NOMMU are painful and given the chance I would always use MMU if available. I don't care if it costs a few percent in performance, it simplfies so many things and helps provide so much more robustness and helps debuging. I guess I really don't understand the desire for uclinux on x86 at all. :) > Shared lib is a nice to have ,but at this time with 4Gig im not worried. > Maybe can use AOT and stat link .
