For Matrox G450 video card 8+24 overlay mode is declared in 24-bits color depth (only with 1 display). But in fact if I put "Option “Overlay” “8,24"” into Device section of xorg.conf than X server is crash with error:
…

What’s wrong?
OS: SuSE 10.2 + kernel 2.6.28 (from kernel.org, built with “make oldconfig”), xorg 7.2-26
Also see complete xorg.conf for details:
(take note of “Clone” and “Xinerama” options are setted to “off”!)
