In theory exists MDA adapter , wich is VGA compatible as secondary.

fbcon is abstract hardware independ layer.
fbcon will work only Zoltan's ruby-2.6.11-mm1. 2.6.0-2.6.9 seems works for
me. For another peoples 2.6.0-2.6.9 gives very conflicting results.
At least matrox g550 is one of (sometimes) working device. I cannot
recall number of kernel, but for me works 3 head box, with Voodoo 1,
Voodoo 2 and Voodoo 3 video. Of course Voodoo 1-2 is VGA-less
abnormal video cards. Normal "ATI 3D rage" alltimes gives blank screen
as secondary card. i talk about text mode only.
IMHO i read about radeonfb N-head capability.
