I suspected that those quirks might still be necessary after having to
accept the s3-bios and s3-mode quirks for the Intel kernel modesetting
driver, but I didn't have anything to test that suspicion against.

We will probably have to annoy the driver developers directly.

I suspect that the Intel driver will ultimatly still require the s3 and
the vbe post, state, and mode quirks.
