[mythtv-users] modelines

[undisclosed]

I have a Rage Mobility card that I inherited... it works fine
for console mode, but X just isn't right... I assume this is
a modeline problem, but I'm having trouble finding a working
modeline for the S-Video out.  

Anyone know of good documentation for XFree 4.x (preferably
4.3) to determine working modelines?  Everything I find is for
X 3.x and doesn't seem to work for me.  Any help would be 
appreciated.
