Public bug reported:

Binary package hint: xserver-xorg-video-intel

Since the sistem was updated to kernel 2.6.31-17-generic-pae or greater (currently 2.6.31-18, and it is what was used to generate bug report), the system (ubuntu karmic gnome) switched to using the vesa driver to to the i810 driver not loading.
As well as what the apport-bug generated, I've attached the relevant dmesg section (gives errors about i915).

This is from the xorg.log

 (II) LoadModule: "intel"
(II) Loading /usr/lib/xorg/modules/drivers//intel_drv.so
(II) Module intel: vendor="X.Org Foundation"
        compiled for 1.6.4, module version = 2.9.0
        Module class: X.Org Video Driver
        ABI class: X.Org Video Driver, version 5.0
(II) LoadModule: "i810"
(WW) Warning, couldn't open module i810
(II) UnloadModule: "i810"
(EE) Failed to load module "i810" (module does not exist, 0)
(II) LoadModule: "vesa"

this is what I get if I try and modprobe i810 manually:

FATAL: Error inserting i810 (/lib/modules/2.6.31-18-generic-
pae/kernel/drivers/gpu/drm/i810/i810.ko): Unknown symbol in module, or
unknown parameter (see dmesg)

and relevant dmesg
[ 4447.404830] i810: disagrees about version of symbol drm_core_get_reg_ofs
[ 4447.404838] i810: Unknown symbol drm_core_get_reg_ofs

[ 4447.406241] i810: disagrees about version of symbol drm_core_ioremap
[ 4447.406245] i810: Unknown symbol drm_core_ioremap

At the moment the work around for this is to boot into the 2.6.31-16
kernel and everything works fine, but it does seem there's been a
regression in an update. I don't have an xorg.conf file, the system
should be able (or used to be able to) select the right settings
automagically.

Hope this is fixed soon.

TIA
