Actually it's pretty embarrassing that we can't change X configurations without restarting the server. It's one of those things so embarrassing that you hope none of your friends finds out about it.
At least nvidia gives us the dynamic twinview experience in the nvidia-settings panel... but like you say, you still have the inconvenience of loading the GUI and changing the settings.
Then again... the last time I booted into Win XP it automagically was no longer able to figure out that I had a dual-monitor setup, and I no longer had the option to select the second monitor in the nvidia panel. I gave up trying to figure it out.
The moral of the story is that computers are evil.
