Bug description:
The fbdev subsystem has been deprecated for a long time. We should
drop it in favour of using simpledrm with fbdev emulation layer.
This requires config changes:
DRM=y
DRM_FBDEV_EMULATION=y
FB_EFI=n
FB_VESA=n (? check this)
SYSFB_SIMPLEFB=y
fbcon will still require FB to be available, but will use the fbdev
emulation layer
At the time of filing this bug report, the NVIDIA drivers don't
support the fbdev emulation layer, so VT's would be broken on them if
this was to be enabled right now. So the drivers need fixing, and this
bug report is a placeholder until we are able to move forward.
