One in-kernel test user we have is the fbdev restore code - it needs to
get rid of all planes, cursors and set up its new config on all crtcs. I
think this would be a fairly nice (albeit really basic testcase): You can
set up a bunch of planes/cursors, then vt-switch to the fbcon - this way
we can exercise the atomic stuff in drivers a bit better even without
needing to add any ioctl.
