Hi JL,

how about describing the actual problem first? I can see you want to 
poke around the UEFI and tweak the supported GOP mode table. What's your 
actual use case, i.e. which guest OS, plus all other facts/context info 
you can give.

What I don't like about your proposal is changing the existing modes, 
because that'll introduce incompatibility for no good reason.
