Trouble with Dual Head Matrox G550

[Tom Tengdin]

I have not been able to get my 3 headed system working since I upgraded
to FC6.
Main, nvidia, display works fine.  
One one mga display I get a noisy picture that leaves streaks when the
mouse moves over it.  The other display has diagonal lines like it won't
sync but they are both LCD widescreens.  

Displays work fine in XP.  

Xorg.0.log and xorg.conf are attached.

Any one have any idea what I am missing?  

Tnx
