Well, you can sort-of get a dumb framebuffer-like effect if you
turn off any acceleration. For the "modesetting" Xorg driver (for
newdrm):
```
Section "Device"
Identifier "Card0"
Driver "modesetting"
Option "AccelMethod" "none"
EndSection
Section "Screen"
Identifier "Screen0"
Option "Accel" "off" # prob. unnecessary for "modesetting"
EndSection
```
The RANDR extension should still work, I think.
Of course this assumes that your DRMKMS is mostly functional...
