Plug&Play drivers have put matters into something of a state of confusion ...
rather like breaking things apart and then reassembling them into a different
direction.  Bear with us, I think we'll have a better solution  than we did
with the old drivers if we can surmount the obstacles.

This actually is the common experience with drivers.  They are useful for
quick turnaround projects but when you have to fine-tune performance, it is
useful to turn off the autopilot and take over the controls.
