how to force radeon kernel module to load?

[Jack Howarth]

   I have a user with a x86_64 Fedora Core 5 machine which we are
having problems getting DRI configured. The Display control panel
in FC5 sets up xorg.conf to use the radeon driver and to load the
dri module. However when we boot the machine the radeon kernel
module doesn't appear to be automatically loaded as X starts up.
The result is that we don't have any devices in /dev/dri. The card
in question shows up as...

(--) Chipset ATI FireGL V3100 (RV370) 5B64 (PCIE) found

which is correct. Has anyone else run into this problem and
what is the best approach for getting the /dev/dri/card0 device
and the radeon kernel module loaded. I had assumed that the
loading of the radeon kernel module will cause the /dev/dri/card0
device to be created. However if I load the module after X
is running I don't get any devices created in /dev/dri.
Is this possibly a bug in udev?
