Use VGA text instead of framebuffer

[bpisch]

Is it possible to use a text buffer instead of booting right away into a framebuffer? I am using a terminal Qemu (I have no other options available) and the only thing displayed is "graphic mode" with -display curses, so it would be very useful to switch instead to memory-mapped VGA text buffer mode.

As far as I know, the VGA text buffer doesn't exist when booting through UEFI. We try to minimize the differences between UEFI and BIOS booting, so we don't provide an option for this yet.
