The issue with qemumips in particular is that it is still using cirrus for
the graphics card, which has been superseded by '-vga std' for a long time:
https://www.kraxel.org/blog/2014/10/qemu-using-cirrus-considered-harmful/

If that is switched, then fbdev backend should be no longer necessary just
like in qemux86_64.
