Hello Chavdar,

I never actually got the DRM stuff to work with any version of the intel
driver, or any other card for that matter. I apologise for the breakage.

You can revert the update in your tree by:

cvs update -dPD 20080129 x11/xf86-video-intel

In the long run we will need the 1.4 server to get DRI, but I guess
we're waiting for the 1.4.1 release. I should note that Blair's latest
update to wip/modular-xorg-server14 broke it for me. Gives me a black
screen when I attempt to start the server.
