You get a ROM image? Because I'm still not getting one, and the opregion
VBT is invalid as well. I wonder if it's a difference in the machines or
in how you're booting it.

I've got the EFI stub enabled in my build, and I'm booting the kernel
directly from refit (no bootloader). I'm not doing any gmux writes to
switch to the IGPU when I boot. Are you doing something different?
