I'm guessing "non-trivial" is used here in the "I don't like this code
so I don't want to touch it" sense. Which, fair enough I guess, but I
really don't think it's that difficult to add. Like, pretty sure one
conditional at the bottom of doPlatformProbe would be about all you
need.

Also: "we advise users not to use xorg.conf" is a bad meme, can we
please stop. It is still the config file. If you need it, you need it.

This means you'll fail to generate a config file under Hyper-V, where
the fbdev device is platform not pci.
