The problem with UEFI is that the fact if you can only get “text” aka VGA text 
mode if your card happens to have the proper firmware and you can set up the 
card… UEFI as such does only provide framebuffer based console, and that 
framebuffer is either linear memory mapped or pure software - in last case only 
KMS console framebuffer will do any good.
