I got some comments on what's needed in irc: - POSTing cards (i.e. cold boot without executing the x86 BIOS code) - maybe not VGA arbiter, maybe yes... < airlied> the only thing nouveau needs t oworry about vgaarb is if you can't disable VGA decodes < airlied> or can't discover how to disable them < airlied> in that case you need to provide a callback to disable IRQs or have a very resilient IRQ handler < airlied> that can deal with memory/io space disappearing < darktama_> the BIOS parser can cope with earlier cards apparently, I started looking at making G8x work today < marcheu> yeah it works for resume, which is virtually the same < marcheu> but since we have other bugs, we can't have multi-card support ATM :) Since I'm not familiar with this topic, I leave the interpretation for you. You can poke these guys on irc :-) -- Pekka Paalanen http://www.iki.fi/pq/
