New widescreen monitor, old radeon card - will this not work?

I have a new monitor with the following specs:
Horiz 31-87 kHz
Vert 56-75 Hz
1680x1050 at 60Hz
Now, this is attached to a windows box with its digital out and a FreeBSD box
with analog via a Radeon 7500 card. On this last, when I put these new
settings into xorg.conf, it is not what actually shows up on the screen. It
ends up being 1600x1000 at 75, says the monitor, more or less, which puts up a
message complaining about it. It's also offset not in focus.
Somehow, using the old xorg.conf file with all the wrong settings works
better. There is a little distortion but not much I don't know why this would
be. Limitations of the driver ("radeon")?
Parts of the old xorg.conf file follow. I'd like to get this set up properly,
Thanks for any help.
