How about this? What do you think?
It's a gross hack, but it should work in preventing regressions.
The proper fix (running the actual initialization before sysctl_init) is not
so easy, as the codepaths are too separate (and this separation is even exposed
to userland).

If the firmware is not found, abort advertising modesetting via sysctl.
