well, that didn't work out. i used the -STABLE drm_agpsupport.c and
agp.c plus the original 6.2-RELEASE files to compile a new kernel.
then using the patched agp_i810.c and agpreg.h plus the -CURRENT
agp_intel.c, i compiled a new agp module to be loaded at the boot
time. but still, i get the previous message of

link_elf: symbol pci_find_extcap undefined
KLD file agp.ko - could not finalize loading

in dmesg. again, trying to load the module i915 at the loader prompt
at boot time freezes the system. it seems that a lot of other files
need to be updated to make this work, and i don't have the time/
patience to do it. but since i've seen the phrase "support for Intel
965 Express Chipset" in the source of some files in the -STABLE branch
( i915_*.* located in src/sys/dev/drm/ ), i guess installing 6.2-
STABLE will give me at least some sort of support for this chipset.

Using the latest snapshop of the -STABLE branch did not help as well
(just as I tried before two weeks ago). I looked at the output when
the system was booting up, and the message below was there
----------
pci0: at device 2.0 (no driver attached)
----------
just like the 6.2-RELEASE that I had installed before. (I could not
install the -STABLE branch for some reason though, but that's a
different topic). So the -STABLE branch does not support Intel G965
yet. Adding the kernel module i915 at the loader prompt was not
useful.
Then I burned the latest snapshop of 7.0-CURRENT, and it seems that it
can recognize the chipset (though maybe not completely) (again, I
could not install this one as well). Instead of the message above (no
driver attached), it did output some other thing (sorry, I'm don't
have access to that system now, and I don't remember what the output
was). However, loading i915 at the loader prompt showed that the
device is still not detected as AGP (drm said "no device, or device
not agp" or something like this). I'll send the exact output
tomorrow...

I don't know what to do next. As far as I have checked the -CURRENT
source files (the ones in sys/dev/drm/), i915-*.* and drm_*.* all
support Intel G965. So it seems the problem is from agp.c (in sys/
pci/) which needs to be updated to be able to detect the chipset as
AGP...

so it seems that the only version of FreeBSD that could, in theory,
support this chip now it 7.0-CURRENT, but that needs to be patched as
well, and nobody could show me a way to backport that to the 6.2
branch. anyhow, I gave up and installed 6.2-STABLE and am using "vesa"
instead of "i810" to bring up X.

thanks for all the help, btw

I am also having problems with the intel 965 chipset. I recently
bought a IBM t61 laptop that has the GM965 X3100 graphics.


I installed under 6.2 RELEASE and did the minimal installation and I
compiled Xorg and Xfce from scratch. I am able to run xfce when I
specify no xorg.conf. However, whenever I switch to console or stop X
I loose my display. I can get X to some what work when I make an
xorg.conf file but I can't get my mouse to work and I still can't
switch to console successfully. Has anyone been able to get 7-CURRENT
to install? Is it stable enough at the moment?
