I'm pretty sure that the card can do a 1080i signal (I
know that my 5200FX can anyway, I run in 720p mode
because it's my monitor's native mode).

In the comment, it says that the monitor preferred
modeline is 60Hz vertical, and 64hHz horizontal, yet
your HorizSync only goes from 29.9 to 51.0.  I think
that if you change that to something like 29.9 to
65.0, you might have a few more options.

Worst case, boot up Windows and run PowerStrip.  It
will generate Linux modelines that will work with your
monitor (although it takes time and patience).
