I have a Dell PowerEdge SC420, which has an on board
Intel(r)CopperRiver Graphics Controller. I installed
FreeBSD 5.4 and Xorg 6.8.2. I can only get X to display
by using the "vesa" driver. I talked to my sysadmin and
he had me run 'pciconv -lv', which produced the following,

I recompiled the kernel, installed it, rebooted and the agp_driver still
does not find the bridge. Does anybody have any ideas on how to make this
work?
Thanks.
