To make DP work for me, I am using packages from the xorg-updates PPA:
http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ubuntu

along with a direct git checkout from the display-port branch of xf86-video-intel:
git://anongit.freedesktop.org/xorg/driver/xf86-video-intel

The most recent display-port commit (May 7) does not seem to work with
anything in x-updates. I reset to commit
8fd7fc619273316143257ae1a56fce86c00051b1 from April 30th and everything
seems stable for me.

I built the intel driver using './autogen.sh && make && sudo make
install' which puts the modules in /usr/local/lib/xorg/modules/drivers
by default. I put the following in xorg.conf to make sure those drivers
get loaded:

Section "Files"
        ModulePath "/usr/local/lib/xorg/modules"
        ModulePath "/usr/lib/xorg/modules"
EndSection

Be sure to remove that section if you ever switch to a packaged driver!

I gave up trying to get KMS (kernel mode setting) and DisplayPort working together. It appears that the necessary code is only just being merged into the mainline kernel:
http://lkml.org/lkml/2009/6/24/19

As such, make sure you aren't using KMS if you want to take my approach.
It can probably be made to work using some kernel branch but I ran out
of time to mess with that. I'd like to know if someone else gets it
working.
