Nope.
I'd imagine that it's a broken xorg.conf configuration.

You do understand that ranting won't get you anywhere - instead it'll
simply annoy the people that might actually help you, right?

Your xorg.conf looks far too complex in my view. (You didn't post which
nVidia binary driver version are you using?)
It seems to be mixing xinerama and TwinView.
Plus, you have multiple concurrent configurations in the device and
monitor sections that more-or-less contradict each other...

Here's a copy of a work TwinView configuration from one of my
workstations. (22" LCD on DVI, 17" LCD on VGA)
Try using it as a reference (Its most likely full of garbage... I've
been dragging this xorg.conf since ~F5 [with minor modifications]...) 
Notice that the MetaModes are disabled - as at least in my case,
TwinView seems to be configuring the displays more-or-less out of the
box.
