No, you're confusing kernel modules with X modules. You can't load X
modules into the kernel and vice versa.

Based upon your chipset, you'll need to modprobe i830. You may also need
the "intel_agp", "agpgart" and "drm" modules loaded, but modprobe i830
should take care of that for you.
After those modules are loaded, try restarting X, and look for entries in
the log file (/var/log/Xorg.0.log) like this [my comments in brackets]:
(II) LoadModule: "i810"
(II) Loading /usr/X11R6/lib/modules/drivers/i810_drv.o
(II) Module i810: vendor="X.Org Foundation"
compiled for 6.8.2, module version = 1.3.0
Module class: X.Org Video Driver
ABI class: X.Org Video Driver, version 0.7
[note that this is the X driver, not the kernel driver]
...
(II) I810: Driver for Intel Integrated Graphics Chipsets: i810, i810-dc100,
i810e, i815, i830M, 845G, 852GM/855GM, 865G, 915G, E7221 (i915),
915GM, 945G
...
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 8, (OK)
drmOpenDevice: node name is /dev/dri/card0

drmOpenByBusid: drmGetBusid reports pci:0000:00:02.0
(II) I810(0): [drm] DRM interface version 1.2
(II) I810(0): [drm] created "i915" driver at busid "pci:0000:00:02.0"
(II) I810(0): [drm] added 8192 byte SAREA at 0xdfdf6000
(II) I810(0): [drm] mapped SAREA 0xdfdf6000 to 0xb7c7a000
(II) I810(0): [drm] framebuffer handle = 0xf0020000
(II) I810(0): [drm] added 1 reserved context for kernel
If you get an error message instead, try replacing your X i810_drv.o module
with the one from this web site:
http://www.fairlite.demon.co.uk/intel.html
Restart X, and if it still doesn't work, post the relevant portions of your
log file.
