Running that specific driver on several Lenovo HD4600 driven models gives me headaches
and more. This software-framebuffer works - yes, on whatever resolution you might wish,
but it consumes CPU time. That said, I recall that the display was jumpy, slow and
unresponsive when used under heavy load - not even 3k resolution, but with a moderate
lowend of 1980x1080.
