This appears to be needed for video output to function correctly.

Hi James, EFI_FB is its own driver and not needed by gma500 to drive its hardware. What makes you think it's required?
I wasn't getting any HDMI video output without it enabled for some reason, I assume it is doing some sort of initialization needed by gma500 during startup.
