This year someone said he/she would look at making it possible to have multiple concurrently active consoles on distinct framebuffers. Hopefully something is happening on that front (that would certainly also include some fbcon cleanup)That would be me.Thanks for showing up (I didn't find the matching thread, probably subject and my search terms were no good friends :)
No problem.

I have a tree at http://git.infradead.org/users/jsimmons/linuxconsole-2.6.git but currently fbcon is broken so I'm tracing down the problem.Thanks for the reference to your tree! What's you opinion regarding my changes to fbcon in my RFC patch? Are they ok or would you prefer having fbcon changed to stop peeking at registered_fb list and just operate directly on fb_info everywhere it needs it? (that is let con2fb_map[] point to fb_info instead of indexes into registered_fb? (I have a preference for the second one and will try it out)
I'm aiming to kill off registered_fb. I agree that fb_info should be used directly and we can avoid the ref-count. As for con2fb_map that is a little more complex.
