Hi Justin. No, it's not broken, at least not the last time I tested. Take care that /dev/mem also contains shared data, so you need to do some phys/virt stuff, not sure how you can avoid that without mmap. Your warnings might point to out-of-memory issues (check with dfbdump using some options) but I cannot tell without seeing which problems you are encountering.
