"its a nice way of Microsoft to implicitly state, "the driver manufacturers can't get their shit together, so we're going to take on a large portion of the work involved". "

They did it for that reason, and because they needed to implement a controlled gfx pipeline, video memory management and device virtualization. The new directX kernel mode subsystem is a very sophisticated (I highly recommend reading some of the published documentation, it's really cool stuff) and, well, the old model just wasn't going to cut it going forward.
