If I remember right, the "-phigh" flag can beimportant in generating your
new xorg.conf file. Manual xorg.conf editing can be fairly tricky, I
personally spent hours playing with xorg.conf under earlier linux versions.
As of hardy work is being done to improve support for dual monitors without
having to manually edit xorg.conf.

Here's a useful forum post anyway that should give a few pointers on how to
set up various types of display.

I've also noticed an error in your server layout. Instead of using screen1
and screen2 (which I'm assuming you've created), a non-existent screen0 is
being used along with screen1. This most likely leads to your low resolution
output as X can't find the missing screen0 and falls back to a default,
which I'm guessing here is the vesa driver.

Remove all the uneeded clutter and keep only what screen, monitor, device
defintions you require (obviously keep, mouse, touchpad, wacom stuff is
alright to stay) and try initially setting up your server layout using each
device/monitor to ensure you have the correct settings.

One last point is that you may have problems using the open source, nv,
driver when configuring a dual monitor setup - hardware acceleration may be
required so it may be preferable to use one of the nvidia, nvidia-glx or
nvidia-glx-new drivers, depending upon your hardware.
