Xorg - radeon & X700 no go?

[Patrick]

Hi all,

I installed rawhide from about 5 hours ago on an Acer Ferrari 4000 with
an ATI X700 and 1680x1050 screen. X was configured with the vesa driver
and 1400x1050 which looks a bit stretched in width. So I
edited /etc/X11/xorg.conf and replaced vesa with radeon in the driver
section. Did an init 3, modprobe radeon and init 5. The screen does not
show anything (stays black) while X seems to load.
In /var/log/Xorg.0.log I see a lot of these messages:
drnOpenDevice: node name is /dev/dri/card[0..254]

Is there any way I can make this work?

Thanks and regards,
Patrick
