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,
hostb0@pci0:0:0: class=0x060000 card=0x01801028 chip=0x25888086 rev=0x04 hdr=0x00
vendor = 'Intel Corporation'
class = bridge
subclass = HOST-PCI
pcib1@pci0:1:0: class=0x060400 card=0x00000088 chip=0x25898086 rev=0x04 hdr=0x01
vendor = 'Intel Corporation'
class = bridge
subclass = PCI-PCI
none0@pci0:2:0: class=0x030000 card=0x01801028 chip=0x258a8086 rev=0x04 hdr=0x00
vendor = 'Intel Corporation'
class = display
subclass = VGA
...so the agp driver is not detecting the agp bridge. We tried
adding 0x25888086 (from the hostb0 line above) to the /usr/src/sys/pci/agp_intel.c
file,

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.
