It seems I been rather lucky with Catalyst Drivers, because my last 2 purchases of graphics cards (HD 3850 and hd 7850) has worked fine for me with Catalyst, i do not know if it is a big difference between brands because both card was from Sapphire, and my next card will probably also be from Sapphire because of this.
Everytime I've attempted to use this crap, I've gotten random hard locks, and it never resumes from sleep, OSS Radeon stack never locks for me, and always resumes.

Because what you changed is a user setting. If you use kdm you could place xrandr commands in
/etc/kde4/kdm/Xsetup
Look for something similar for lightdm. I doubt that there exists a config tool to do so, that has absolutely nothing to do with nvidia - would be with oss drivers the same.
