Forget all these calculations for now, I noticed this in your log:

2007-08-15 23:24:38.292 VideoOutputXv: Falling back to X shared memory
video output.
                              *** May be slow ***

You will want to fix this first before worrying about the aspect ratio.

I also figured out the wacky pixel dimensions of 1920x1143, it looks
like you actually have a 1920x1200 screen, presumably a 16:10 screen
some application is somehow stealing a portion of that away. This
shouldn't be a big worry though, you just have to get the display
dimensions in millimeters correct. Run "man xorg.conf" and look for
DisplaySize. The latest nvidia drivers ignore this, if using those
look at their documentation for the nvidia proprietary version of
the standard DisplaySize option.
