GoogleEarth accelerated problems - Intel 82830 i915 module OpenGL Tungsten Graphics Video Driver

Hi - Help - Please tell me - which mailing list should I address this
question to? (Note: I've tried the dri-users at lists.sourceforge.net, but
got no replies there. Is that the correct place? Is there someplace
better? Like, for the Intel 82830 video driver sw?)
My laptop with an Intel 82830 wont display GoogleEarth properly in
accelerated graphics mode. lsmod shows i915 loaded. If I tell the system
to use another driver (i830 ?, IIRC), GE displays _properly but 10 times
slower_. (I'm guessing it's doing sw emulation, no hardware
acceleration?) Using latest released Kubuntu, on Sony Vaio.
I found this thread which seems like my problem:
Intel Integrated Graphics display problems
http://bbs.keyhole.com/ubb/showthreaded.php/Cat/0/Number/456558/an/0/page/0
"The OpenGL over lay dosn't seem to line up properly with the display
window and the on screen controls don't line up with the place where you
have to click to use them. The Overlay tends to move about when you
resize the window and a lot of display rubbish gets left behind around
the edges."

I'm guessing it's due to the graphics accelerator chip sw, since the
emulation(?) works fine.
Any idea which mailing list is for the sw creators who handle the intel
82830 hw?
Any idea how to isolate the sw that is the problem?
Or a fix?
Note Ubuntu should release their next version this October, with a later
X - X 7.1 ?
I think the current version might be 6.?? 6.8? 6.9?
[The Adept package manager shows xserver-xorg installed, ver
7.0.0-0ubuntu45]
Is there a better mailing list to ask this question? Maybe a developers
list?
Thanks! :)
==================
it's got the i915 module loaded,
& is running fast but with messed up window structure:
$ lsmod | grep 915
i915 21664 2
drm 78484 3 i915
$ lsmod | grep drm
drm 78484 3 i915
agpgart 36784 3 drm,intel_agp
$ lsmod | grep agpgart
agpgart 36784 3 drm,intel_agp
$ lsmod | grep agp
intel_agp 24700 1

now - nothing added
before - "i830", or "i915"
------
/etc/X11/xorg.conf:
Hmmm - I don't know why it says "i810" here now.
It did say i830 at some time previously.
(I think it was when I had the "i830" here that it ran slow but
unmessedup.)
