Subject: Re: Problems with low hsync with nwn on Gentoo
Since "normal" 1024x768 mode worked, I just defaulted back to that mode
and used xvidtune to show the full modeline. Here's the final one I'm
forcing 1024x768 to be:

ModeLine "1024x768" 94.50 1024 1072 1168 1376 768 769 772 808 +hsync
+vsync

(excuse the wrap-around).

This seems to work well.
