The FCode ROMs supplied for CG3/TCX are used to both initialise various
DT entries for the graphic adapters and also provide a minimal driver to
allow OpenBIOS (or Sun PROM) to initialise and use the adapter at boot.

I'd say at the moment the error should be fatal, since the correct way
to have a headless system would be not to have the virtual graphics
adapter plugged into the system in the first place. Otherwise I can see
that the skeleton DT nodes generated by the PROM would be missing
several properties generated by the FCode (such as the framebuffer
address), which would be utterly confusing for any client trying to use
the graphics adapter.
