I haven't fixed it up but I do have a idea. It would also eliminate that 
awful driver init list in fbmem.c.  The idea was to send a event when a 
driver is registered. Then fbcon would recieve that event. Then it would 
look at the con2fb_map in fbcon to see what VCs to map to. At the boot 
command line or via con2fb you can set this mapping. Now if you have the 
case of a dual headed card where one head isn't mapped then it could 
default to mirroring. Fundamentally we need a mirror api for the fbdev 
layer. I'm hoping to introduce that via sysfs.

So it is possible to run OpenGl on a Matrox card :-)
