I mean, the modern systems that *need* GPU firmware generally seem to
do pretty well with using native resolution and don't perform too
badly, especially in the simple installer UI. When I test the fallback
path on my bare metal test box on UEFI it uses the monitor's native
resolution and performs fine (even, honestly, in GNOME), and that
motherboard is nearly a decade old even. Don't know if this is the same
for everyone, of course.
