That's what I'm talking about. When booting with VESA as a fallback,
people (like me) would still like to use their native resolution, and this
resolution is exactly specified in the Additional VESA modes section, as
far as I can see.

me ping AMD and see what they think.
That would be great. Thanks for your effort!
