This will actually try to set the mode right?

SDL does it this way and its caused me some pain dealing with
framebuffers on hardware that has issues with certain modes.  Its also
a good bit slower for the app to startup while the code crunches out
the pll settings.

From a users perspective I think advertising valid modes is a good thing.
