DRI enabled, but not used, even though card supports it.

Yes. I have an Intel 845G running on an i810 driver. I know for sure that this driver supports DRI Hardware Acceleration. I've set all DRI options to be enabled, yet, when I restart my computer, I check to see if the acceleration is enabled, and it isn't... What is it that I could be doing wrong?

(I will post the Xorg.conf file in my next post.)

Update 7-30-05:

I've installed the latest common and i915 snapshots from and my problem has changed slightly.

Before I installed these snapshots, Xorg.0.log would report something along the lines of "module 915 not found, disabling DRI."
Now that I have installed them, Xorg.0.log instead shows
(WW) I810(0): Direct rendering has been disabled.
(EE) I810(0): [dri] DRIScreenInit failed. Disabling DRI.
No errors beforehand. However, I did find this interesting blurb some lines after the "Disabling DRI" line:
(II) I810(0): direct rendering: Failed
(==) RandR enabled
Symbol noXFree86DRIExtension from module /usr/X11R6/lib/modules/extensions/libdri.a is unresolved!
But glxinfo | grep rendering still reports "direct rendering: No".

To think, I'm doing all this just to get 3D to run at a decent speed.

Would anybody who has successfully gotten DRI to work with an Intel 845G (Or any of the cards supported under i810) under kernel 2.4(.29) please give me some advice on how to get it working?

Reason for bump: Edited post with out of date info. I have researched other means to fixing this issue, but still no luck. Read above post for more info.

While doing an lsmod (for some other sound-related issue (microphone)), I found this interesting bit in the listings:
i915                   66728   0  (unused)
Could this have something to do with the DRI issue, or is it just a false alarm?

Urgh. I just tried the drivers from the Intel site.

I ran glxgears after installing them and restarting... the framerate's even worse!

And I also get this now:

(EE) I810(0): [dri] I830DRIScreenInit failed because of a version mismatch.
[dri] libDRI version is 5.0.0 bug version 4.0.x is needed.
[dri] Disabling DRI.

EDIT: Compiling kernel now...
