I've got a pretty much identical setup, and direct rendering is going. Sounds like you've covered most of it, the only thing that springs to mind is that in at least the later Xorg's, if not all of them, you're meant to use the i915 module rather than i830.
The naming there is pretty confusing - basically the i830 module is for i810, i830, i855 and i865 under XFree. The i915 module is for i810,i830,i855,i865 and i915 under Xorg.
Looks like a kernel recompile may be in your future :-)

I was running gentoo-dev-sources 2.6.7-r14 kernel and had an issue with the i915 driver included in the x11-drm package. I patched the kernel with the following patch and built the resulting i915 driver. Seems to work much better. The patch has been successfully tested with 2.6.7 and 2.6.8.

yes i also tried i915 divrer but there is also dri : NO.

mayby i should change the xorg.conf and sustitute i810 with something else ?

kaputt : u built new i915 driver or there was no in the kernel. i ask as ive got it in my kernel ...

The i915 driver hasn't been officially included in the kernel and gentoo-dev-sources hasn't started to include the patch yet, so I patched the kernel manually and was then able to select and compile the driver.

If it would help, I can send you a copy of my kernel and xorg configs so you can compare. Just let me know.

@kaput

How did you configure your kernel?

do you have i915 as a module ?
do you have agpart as a module?
Do you have Direct Rendering Manager (DRM) enabled in kernel?

Ive tried the i915 driver and couldnt get the dri working under xorg 6.8.

Got it working on both now.

Used the i915 driver on the vaio and i830 one on the compaq. Compiled that and all the AGP/DRM/DRI stuff driectly int o the kernel.

Kernel: gentoo-dev-sources-2.6.8-r3
X: X.org 6.8.0

Just needed to add this section to my xorg.conf to give users permissions to access DRI:

i have a centrino notebook with i855GM.
i'm using gentoo-dev-sources-2.6.8-r10
for DRI/DRM i have x11-drm-20040827 installed with the i915 driver.

i have agpgart compiled into the kernel, no DRI and no DRM in the kernel as it should be provided by x11-drm (and there is no i915 driver in the kernel)

in my xorg.conf i have enabled

=== EDIT ====

Ok worked it out. You need to be in the /usr/src/linux directory then go
patch -p1 < "Path to patch"

thanks.

I am trying to run the patch to. I have not patched any source before so need some help. Do I copy the entire code from the link to the i915 patch provided at the top, save it and then run the patch -p0 <<path> against it or should I only copy the lines from the

I finally solved my direct rendering problem and post it here in the hope it will help someone. My problem was that I've got a intel820 card. I'm using the i810 drivers, because x won't start otherwise. Today I added 3dfx in my use flags and recompiled X, but still no direct rendering. Then I saw that hotplug had not loaded intel_agp (I trust in hotplug), but only intel_mch_agp. When I manually loaded that direct rendering worked

Instead I resolved using the i915 module in the new 2.6.9 kernel.
Neither the patch to 2.6.8 nor the x11-drm managed to work for me.
Now I get 2000FPS with 100% cpu utilization (Acer TMLCi: Centrino 1,3G & 855GM)
