Just pushed to drm-misc-next, fix is correct.  bochs video memory is a
pci bar, and the framebuffer is stored there.

Using sys instead of cfb is probably a leftover from cirrus, where the
framebuffer actually in a shadow copy in system ram, due to the low
amout of (pci) video memory.

cheers,
  Gerd
