Intel 865G and X.Org 6.8.1

I am using X.Org 6.8.1 as shipped with Slackware 10.1. My
graphics adaptor is identified by lspci as follows:
00:00.0 Host bridge: Intel Corp. 82865G/PE/P DRAM
Controller/Host-Hub Interface (rev 02)
My xorg.conf file uses the i810 driver.
The problem is that, although I can use X all right, according
to glxinfo direct rendering is not supported. Since I understand that
the 865G chipset supports direct rendering, I guess that I must be
doing something wrong.
Here is some more info:
1) The relevant modules that my 2.6.11 kernel loads are
intel_mch_agp, intel_agp, agpgart. In my kernel/drivers/char/drm
directory I also have drm.ko, i810.ko and i830.ko, but those get never
loaded. I tried loading them by hand (in several combinations) and
restarting X, but still no direct rendering.
2) In /usr/X11R6/lib/drivers I have i810_drv.o, which indeed
is the module loaded by X. I can't see any other modules that have to
do with Intel graphics chipsets though.
4) In /usr/X11R6/lib/dri I have i810_dri.so and i915_dri.so.
I think that my X server attempts to load them both, but fails; here
are (what I reckon to be) the relevant lines in my Xorg.log file:

I am kind of lost on how to proceed. My immediate questions are:
1) Is it indeed possible to have direct rendering support
with the hardware/software I am describing?
2) What combination of kernel modules and X modules should I use?
Here is, for completeness, the xorg.conf file that I am using:
