PCI Express

[marco.borsatino]

After a succesful installation on an AMD64, I started configuring X environment; 
I use an ATI Radeon X700Super PCI Express, which is not listed by "xorgconfig"; 
I got help from an italian FreeBSD user, and I modified "xorg.conf".
When I startx I get this error:
----
(WW) RADEON: No matching device section for instance (BusID PCI:1:0:1) found
(EE) No device detected
Fatal server error:
no screens found
----

This is a part of my xorg.conf, modified according to the suggestions of the italian user.

BusID definitions comes from "/var/log/Xorg.0.log".
Any idea?

Thanks.
