Lack of /dev/vtvga0?

Hello list,

As I've mentioned in a previous message, I've been working on trying to get a
proper graphics subsystem/desktop up and running under 12-CURRENT without any
X components; something that was once possible a long time ago by using libvgl
probably via SDL1.2 — an option that's been deprecated in SDL2 and isn't
viable in all cases since libvgl doesn't support newcons/vt.

I understand the limitations of the basic VGA driver (lack of hardware
acceleration, current hard-coded 640x480x16 resolution) but I'm not clear on
why the vt_vga driver does not make a framebuffer device available (vtvga0 is
initialized, but there is no corresponding /dev/vtvga0). Isn't it possible to
use vt_vga in pixel mode and directly write to the kernel console framebuffer?

Any insight would be appreciated!
