Since we also need something like this in the DRM, and since it's there now for Radeon, why not put it there? I guess I'm just confused about the relationship between fbcon and DRI. There seems to be too much in fbcon that could be common to both systems, and similarily the other way too. -- Billy Biggs [EMAIL PROTECTED] -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-dev" as subject.
