There's a bug open for this issue and a test patch available:

Does the 'modetest' program work for you? It's part of the drm repo...
Also have you tried git master of the xf86-video-intel driver? AFAIK
2.6.3 should work ok but there have been many fixes added since then.
Also be sure all your package versions will work together, Carl
recently ran into an issue where one or more was incompatible (silently
unfortunately) leading to a hard hang at server startup.
Another thing to try is a totally stripped down session. I.e. boot
into console mode only (with the new KMS console), and start X with
just an xterm (e.g. echo "exec xterm" > .xinitrc; startx). It'll help
narrow things down.
