Do you really think that it is really needed to include all modesetting
stuff to the FreeBSD kernel? What's wrong with the current
implementation for the, say, Radeon userland drivers in this respect?

AtomBIOS and company needs not to be in the kernel. Sure, DRM is
already a part of the kernel, but it is the "real" need -- physical
access to the hardware (with the more-or-less fast response) is needed.
But what is the point in having the pure userland code in the kernel?

I understand that Wayland has only 3000+ lines of code, but I feel
that the complexity is just moved to the other places. Am I missing
something?

I feel that GEM is rather useful for the DRM layer itself? At least
it is that it was written for...
