Why is the user using nvidiafb?
This exposes a bug in nvidiafb, The user shouldn't even be using the
driver, it does nothing on their hardware, but it does a lot of things
before it binds.
nvidiafb should be fixed to probe the hw to see if it supports it
before it removes the framebuffer. I don't think reverting this patch
in full is the right answer, though we could revert the core bits and
allow nvidia fb to limp along until it's fixed or shot.
