Only a 700Mhz with 12" and a 16MB Radeon Mobility, yet with (some help)
I have a working drm-trunk X, quake2 runs nicely :)

There relevant part from the .config from my 2.4.21-benh2 kernel would
be this [1].

You will probably need the radeon.o kernelmodule for drm which differs
from the one that comes with the kernel.
To get this do 'apt-get install drm-trunk-module-src', den untar
drm-trunk.tar.gz in which is now placed in /usr/src and to a 'make' to
get the sources installed. Also have the benh sources at /usr/src/linux
so that these and not some older kernelheaders are linked.
Place them in /lib/modules/<kernel-version>/kernel/drivers/char/drm/
(backup the old radeon.o first i'd say) and run 'depmod -ae'.
(Yes, there is a 'debian-way' to install kernel and probably modules to,
yet I still to this via cp vmlinux /boot/ and make modules_install ;-)
Then you need might need to edit your XF86Config-4 and
'Option "AGPMode" "1"' (which works for me, other values make X
crash) in the Section "Device", also 'Option "UseFBDev" "true"' should
be set.
Further set DefaultDepth to 16 which is optimal for 3D acceleration.
You will also need to apt-get install xlibmesa-gl1-dri-trunk (i forgot
this one).
Also you I needed the agpgart module loaded *before* the dri radeon
module, for this I just added [2] to the 'start)' section of the kdm
startscript in /etc/init.d. (The Debianway would be.... ?)
_Warning_: My iBook crashed when the dri radeon module was loaded
without the apggart module so always have a seperate kernel with the
plain radeon module so that you can atleast get a commandline to fix this.
If it still doesn't work check the XFree86.0.log in /var/log or just
start log in as root in a console just type 'X', the messages will then
just show up in the window.
I think that was all I did to get dri up and running.
