I have an older 46" Mitsubishi TV connected via an RGBHV breakout
cable. I've wrestled quite a bit with different modelines and finally
settled on a 960x540p mode. I remember having the problem you describe
with the display wrapped, but it was wrapped for everything, not just
the nvidia logo. I can't remember what modeline/configuration I had
that problem with. Here's the modeline I'm using:
ModeLine "960x540p" 37.26 960 976 1008 1104 540 542 548 563 +hsync
+vsync
The TV is a Mitsubishi WT-46809, and it interprets that modeline as
1080i. It has been working very well for almost a year now.
My system configuration is quite a bit different from yours:
Fedora Core 4
X.Org 6.8.2
Nvidia driver version 1.0-7676
Myth built from svn version 6905
