I would say that you only want to replace the intel video driver.
Zhenyu said it should work with the Xorg-7.3 stack. So, I have no idea
what's in Kubuntu 7.10, but you can just give it a shot. Install all
the devel type packages for Xorg. Go to the xf86-video-intel repo you
checked out. `git checkout origin/xvmc' and build away.

If you don't want to alter the Ubuntu files at all, you can probably
use --prefix=/usr/local. Then make sure that the linker and Xorg will
use the paths there first. I.e., put /usr/local/lib first in
/etc/ld.so.conf and add a ModulePath "/usr/local/lib/xorg/modules" in
the Files section of /etc/X11/xorg.conf. See xorg.conf(5).

That should be it. Read /var/log/Xorg.0.log to see if the new paths
are picked up. You can try to use the lsof command to see if the new
libraries are in use, too. `lsof
/usr/local/lib/xorg/modules/drivers/intel_drv.so' should show Xorg.
