CSM BIOS for EFI machines (Announce)

I guess it would be possible to modify the framebuffer BAR but it would break UEFI graphics driver without notifying about that and also there would need to be enough free space under 4GB. As modern VGA has over 4GB VRAM it might be problematic. I don't know how much space wastes the MMIO of modern GPU. Enginners may tend to not take much care when they have 64-bit address space... :P
