I'm not clear if you're already possibly referring to this=2E But have
you tried sc(4) ( SysCons )=2E If you haven't tried already;
adding the following to your loader=2Econf(5) should give it to you:

kern=2Evty=3Dsc

You can also include it in your custom kernel by adding this to your
KERNCONF

device    sc
options   SC_PIXEL_MODE  # adds support for the raster text mode

Hope this helps=2E
