During last few days I was playing with multiple monitor support for recent
2.1.X kernels and I will release an experimental patch soon. Currently vgacon
combined with fbcon works for me, but I'll have to hunt down few bugs.

I also see no advantages in having VGA/MDA handled as frame buffer devices
instead of driving them by a stand-alone console driver (i.e., vgacon or mdacon).

Have a nice fortnight
