 OK, so this is what needs to be done for the bootup to get past console:
 radeondrmkmsfb is a subdevice. In macppc land this means that is_console wo=
 n't be properly set. So do a check if the device is a "radeondrmkmsfb" in t=
 he ofw autoconf and then set is_console if so.
 Then to avoid the wsdisplay assignment issue, avoid setting is_console in c=
 opy_disp_props if the device is a "radeon." (For safety measures, we can sk=
 ip copy_disp_props if the device is a "radeondrmkmsfb" even though it won't=
  have an OFW node unlike "radeon.")
 
 This gets us far to the point that radeondrmkmsfb will now open up console!=
  However, it is not much, as we get a blank screen shortly after due to the=
  driver somehow not being able to get the CRTC clock from the selected disp=
 lay mode. This is probably with how it hates the laptop panel? If I plugged=
  in a TV cable maybe I would get something.
