Gratz :)

Although, I think it would be possible with Linux but you would have to use a DIY distro like Gentoo that doesn't hide all the features behind a cascade of automagic system management UI-dialogs or scripts. That being said, haven't done a customized Linux installation for years now, since FreeBSD + documentation enable me to more easily create a customized FreeBSD installation for spesific tasks.

That must be because UEFI depends on kms.ko to get a framebuffer console. In this case it would be the kms/VESA module. So probably there's some kind of race condition between the kms/VESA framebuffer and nVidia kmod.

Have you already checked if there's any PR about this? If not, you could make one. I am sure this could be fixed easily.

Hmm, this is something you should definitely make a PR for, if you can. Your description makes it seem like the BSDInstall scripts are a bit behind the actual UEFI boot stack.

Thank you for describing your use case. This is valuable information :)
