i810 is what displayconfig-gtk produces in Hardy. When I replace i810 on
my 845 chipset the screen (MegaImage 17 and Hitachi SuperScan Elite 641
.22 mm) refresh is totally out of sync and I need to Alt-F1 to modify
back to i810. Perhaps the intel driver works in Intrepid (the OP's
system) but it breaks mine in Hardy. With the i810 I also get full
compiz effects etc. (again with Hardy). From lshw on that machine:

*-display
             description: VGA compatible controller
             product: 82845G/GL[Brookdale-G]/GE Chipset Integrated
Graphics Device
             vendor: Intel Corporation
             physical id: 2
             bus info: pci at 0000:00:02.0
             version: 03
             width: 32 bits
             clock: 33MHz
             capabilities: pm vga_controller bus_master cap_list
             configuration: driver=i810_smbus latency=0 module=i2c_i810

So, I reckon that Shiva can try replacing 'i810' with 'intel' as it
appears that i810 is depreciated in Intrepid:

http://packages.ubuntu.com/intrepid/xserver-xorg-video-i810

but then, maybe that's the problem... depreciated/transitioned drivers
that work in 8.04 but not in 8.10 (nvidia for example). I'll load up the
second hard drive on that machine with Intrepid tomorrow and test then.
