Indeed, there are lots of pitfalls. The problem with the BAR method is
that not all PCI graphics boards map the framebuffer with BAR 0x10 and
then of course BARs are a PCI thing. Maybe we should add an ioctl that
returns the framebuffer offset and size, this would at least work on
non-PCI devices as well.

have fun
