If you configure it in the following should work on GMA500/600
- internal laptop displays including backlight
- external svga
- mode setting via KMS
- framebuffer console
- the framebuffer X server (and once out generally Dave Airlie's generic
  KMS X server)
- suspend/resume

The following I know don't work
- Huge external displays so large they won't fit in 8MB at init time
  (causes a crash)
- Using the vesa X server with it - this confuses stuff and isn't
  fixable, it's a "wrong user configuration"

Unsupported
- 2D hardware acceleration except console scrolling (as it seems to be
  too slow to be useful). I may add some 2D bits later where they do help
  (eg back to front blitting may be worth it just about)
- 3D engine (no public documentation)
- Video playback acceleration. In theory there is enough info in the
  VAAPI code for GMA500/600 that has been published and in the old
  'binary X/source kernel' driver to do this but someone will have to
  work on it if they want it
- Dell Mini HDMI port. This seems to be some kind of external bridge
  chip. Being a TV luddite I don't yet own an HDMI capable display to
  test.

And I'm sure we have a few bugs left !
