The user mode driver would have full support for mode > setting/edid in user space libraries. That would need proper synchronisation with whatever kernel driver does command processing (something we +/- lack today as well) since we must stop it when doing mode switching. Actually, I much prefer keeping the mode setting driver in the kernel (like any other OS btw). While the accel stuffs location is debatable (best option beeing what DRI does imho, that is a kernel module taking care of sending the command blocks & dealing with irqs, while the actual constuct of the command blocks goes to userland).
