Hello, I have a similar problem on a laptop with hybrid ati/intel dual graphics.
I've managed to get it working by blacklisting the i915 module and got to where you were at with a blank screen but an ok xorg.log
I tried fiddling with the brightness controls on the laptop and it worked, so you might try that.
I hope this SNA support eventually lands on testing to see if I can use the laptop without all these fiddly configs.
