From what I tried mainly seems due to dri (and occurred also on other chipsets [other than KT133], with other resolutions and depth [like 24/32bpp and 1024x768] like VIA Apollo Pro 133T as well as AMD761). Comment the line 'Load "dri"' in XF86Config-4 and the crash would go away (otherwise OOo and SO6 are almost unusable). Unfortunately doing that you'll loose 3D acceleration. The problem is quite weird (mainly occurs when dealing with fonts, or scrolling but seems not related to freetype or some wrong font) and also occurs using other kernels and XFree binaries as well as with latest Matrox CVS DRM/DRI or with XFree compiled with Matrox HALlib enabled. Alternatively could be agpgart but mga module doesn't build without it. Bye. Giuseppe.
