> Using supported VGA-Card (ATI Radeon 9250 PCI), which is recognized at boot time, starting Xorg reboots the machine ungracefully, if the dri-module is uncommented in xorg.conf. This is the case in the default xorg configuration file generated with Xorg -configure. Commenting the line 'load "dri"' in the section "Module" of xorg.conf makes the problem go away. The card worked with dri hardware acceleration in a previous FreeBSD/i386 installation on a different mainboard/cpu. The Problem started when changing the mainboard and CPU. Current CPU is Pentium D 805, current Board is Asrock 775Dual-880Pro with VIA PT880Pro Chipset and 1GB DDRII Ram in dualchannel configuration.

I've got an X300 based card in a test system.  I know 3d isn't
supported on this card but dri.freedesktop.org says 2d hardware accel
is. I seem to recall dri 2d accel working on 6.0. But when I try
loading dri in 6.1 the box just totally locks up.  Uncommenting dri in
xorg.conf isn't really a "fix" but does let me load X....
