That's unfortunate - setting CONSOLE_VGA also causes coreboot to try
and write to the vga screen.
I would think coreboot should always configure the legacy PCI bridge
bits and CONSOLE_VGA should just control whether or not coreboot tries
to write to the screen. (Or, if there is a reason to not configure
the pci ranges, then make it a separate config item.)
