the thing is that with video, more was moved out than was possible while still keeping the system reliable.

note that most of the driver is still in userspace, it's only a tiny portion that's been moved in to the kernel, just enough to be able to track (and set) the video mode.

to butcher a quote
things should be as simple as possible, but no simpler

this is just a small correction

Memory management is also in the kernel (again, because it has to be, you can't share that sort of thing between multiple instances of Mesa, and you have multiple instances of Mesa all the time because the apps often have their own instances rather than going through the X server, for performance reasons). The command stream checker also obviously has to be in the kernel, to protect against a malicious userspace.
