I am sorry, I meant video controller or card. With UEFI world, the boot loader can access console device either via UEFI terminal emulator (SimpleTextOutput protocol interface) in “text” mode, or by using Graphics Output Protocol (GOP). GOP does provide Blt() for Block Transfer, to draw data on console display, and may provide linear framebuffer (address, size and 32-bit depth). It *may* be implemented on top of VGA/VESA BIOS interfaces, but such details are not exposed.

Once we start the OS kernel, the UEFI protocols will be not accessible any more (UEFI Boot Services will be disabled), and OS drivers must implement the access to hardware. If you happen to have gfx card without VGA/VESA support, then X11 VESA driver will not work for you (obviously).
