I have uploaded my xorg-configuration and the logfile from the last 
crash to my server:

http://www.8ung.at/mmax/xorg/xorg.conf.quad
http://www.8ung.at/mmax/xorg/Xorg.0.log.crash

If i use any of the following lines:
#    Screen        "Screen_2" LeftOf "Screen_1"
#    Screen        "Screen_3" LeftOf "Screen_2"

the X crashes after startup. Just the two Matrox Screens or any other 
Cards (Trident and Ati) operate well but if configure all 4 together i 
get a really bad display on the matrox output and the system stucks and 
needs a reboot.

And some pictures:

Just using the two outputs of Matrox MG450:
