With stock Debian 3.14bpo kernel on wheezy, video works.
With a custom build of 3.14bpo kernel (turning stuff off),
it only works with "nomodeset".
Without nomodeset, Xorg.0.log says
    [...]
    [    24.879] (WW) xf86OpenConsole: setpgid failed: Operation not permitted
    [    24.879] (WW) xf86OpenConsole: setsid failed: Operation not permitted

    [...]
    Fatal server error:
    [    24.907] no screens found

And the screen stays black.

I can set the brightness in /sys/class/backlight/intel_backlight/brightness
but the screen stays black.

When I boot with splash, *plymouth* works, but when xdm starts the screen goes black.
