Ok I got it working. I've got the fast nvidia driver installed and working, twin view or "dual head" working with georgeous resolution.
What I ended up doing was as follows.
Installed the nvidia driver.
Within this installation I was asked if I wanted to let the installer try to configure x for me (it created a backup even if it messed up but it did fine). Here's what the installer did. It included FOR me the Load glx line which i had earlier commented out for trouble-shooting. So I just deleted the line I did have commented out for it (redundant useless info). Also the installer did change the driver line to 'nvidia' for me, but it was good to double check on it.
Finally I rebooted to check if the nvidia module loaded during boot by itself or if i would have to probe it manually. I then remembered I already had 'modprobe nvidia' in one of my startup scripts so it was all taken care of. I have a flawless X <=> Fluxbox system right now.
I want to again thank you two for all your help on this issue. Especially to piete for writing such lengthy responses, it must have taken you a bit of time and I truly appreciate it. Thanks guys or gals for helping me so much.
