An added bonus is that if you have multiple video cards or a dual head
configuration with each head on a different fbx device the 5,255 device
would figure out which console you are on when you start the program and
use the appropriate fb device.  Once the radeon dual head code gets
written I'll have to try to start X on fb0 (head 1) and leave the fbcon
running on fb1 (head two).

I was wondering if it is possible currently (kernel 2.6.5) to
have 2 differents video cards in 2 differents VCs and in 2
differents fbdev's.  I have an old trident pci card and one
radeon agp card.  I want to run X (Xfbdev) in the trident one
and mesa-solo in the radeon one, is that possible? how?

Yes, I've tried that in 2.5.x, assuming nothing broke in between.  You need a 
utility to map which console to which fbdev (con2fbmap?).  However, you can't 
use them simultaneously (switching to one console inactivates the other), 
that's for the ruby project.

I have written a graphics server that scans for video cards (via
libHAL from fd.o) and spawns a thread for each card, I have the
support in place for differents cards (with multi-desktops or
Xinerama like in the same box).  All I want to acomplish is to
have 2 (or more) differents fbdevs rendering to different monitors
in the same time.  Currently my server enables DRI (old mesa-solo)
for supported cards (mostly AGP ones) or mesa-fbdev for unaccelerated
ones.  The problem is that without X i can access only the primary
card (the one set it up in the bios) but if i try to load the fbdev
module for the second card it simply will not work.
