In the general case, it's harder to resume systems using framebuffers
than systems that don't. The contortions that are necessary for non-fb
systems tend to break fb systems (you end up with userspace and the
kernel both trying to get the graphics hardware back into a sane state),
so in an ideal world resume would work without any framebuffer support.
