That would be enough for me for entering the LUKS password.

There are several problems with that.
1. No UEFI based firmware is used, but a coreboot based one.
2. To boot fast, I like to load the Radeon/AMDGPU driver directly, and not
spent precious milliseconds loading other display drivers (efifb, corebootfb).
Not having to include these makes the Linux kernel image a little smaller and
loading it faster.
3. Currently loading `radeon` on an ASRock E350M1 and Asus F2A85-M takes
roughly two seconds, which is longer then the OS needs to start. So it’d be
great to be able to load the firmware while GDM for example starts.</pre>
