New Monitor Weirdnesses or how do I get Xorg to pay attention to my xorg.conf file?

I recently had to replace the monitor on my desktop machine (running CentOS
5.11 w/Xen), but I am having trouble getting a *sane* display resolution.
First of all this is an 'older' machine (about 5 years old), with a ASRock
K10N78 motherboard with integrated video: VGA compatible controller: NVIDIA
Corporation C77 [GeForce 8200] (rev a2). I have the stock CentOS 5 Xorg
XOrg is using the vesa driver, since the NVIDIA GeForce 8200 is not supported
by the nv driver (xorg-x11-drv-nv-2.1.15-4.el5). This has been *normally*
fine by me -- my old monitor was a 17" 4:3 monitor that worked just fine at
1024x768 resolution. *I* have no need for 3d acceleration. The NVIDIA
semi-closed driver is not supported under Xen, so hassling with that is not an
option (and if that was the *only* solution, I'll just have to return the
monitor to BestBuy and get something else, probably a more expensive 4:3
monitor from Amazon). The new monitor is a NOC model 1970 and it is a 19.5"
16:9 LED monitor. It only has a VGA connection -- DVI or HDMI are not
I have tried to set suitable mode lines in my xorg.conf file, but Xorg seems
to be ignoring them. Why is this? What 'magic' do I need to perform to get
Xorg to behave? Right now it is coming up in 1024x768 (which is a 4:3
resolution). I want *square* pixels, so I want a 16:9 display resolution.
How do I make that happen? The Xorg log file and my xorg.conf file are
