Selecting a display driver

I'm still trying to get my laptop with integrated S3 savage chip to use dri. I've found some good resources, but I still have a couple of concerns that I hope someone can help with. I've already mailed about the first problem (modifying xorg.conf). The second is that SaX2 currently reports my display driver as "savage" and xorg.conf has the line Driver "savage" in the Device section. I assume this corresponds to the file /usr/X11R6/lib/modules/driver/savage_drv.o (but I'm not sure how to check). The problem is that I think the driver I need to compile will end up as /usr/X11R6/lib/modules/dri/savage.so and I'm not sure how I can make xorg use this file instead. -- Paul
