I have a problem with the i915 intel driver's modesetting. With modesetting enabled, the screen turns blank. I have tried to compile the driver built in, as a module and modesetting both enabled by default and disabled by default (tested with X).
I have tried kernel 2.6.36-r5 and 2.6.37. None of them works. The 2.6.36-r5 kernel reported an error that the bios didn't allocate any shadow GTT. This seems to work using the 2.6.37 kernel:
This is the dmesg output from when I load module i915 or start X. It looks to me like everything is fine here.

I have modesetting enabled. I don't think that it is my kernel config that is wrong. At this point I have no idea what's wrong, but the dmesg output looks ok. I've tried with both the 2.13 and the 2.14 xf86-video-intel versions.
I use i915.modeset=1 as a boot flag and build the i915 driver as a module with modesetting disabled by defaut in the kernel config so that I'm able to boot up without getting a blank screen early in the bootup process. I've also tried every option with modesetting enabled or disabled or i915 build in or build as module without any luck.
Update: After some more research, it looks like the problem is that the monitor is not giving the correct EDID information. I still haven't found a solution.
The manual doesn't give me that information. Only that it is a 13.3" screen with resolution 1366x768. It's a Sony Vaio laptop VPCY21AFX [Sony's esupport].
I don't think it's a MTRR issue, as this should be ignored when PAT is enabled?
When I tried to connect an external monitor to the laptop's VGA port I got graphics on the external monitor.
Update: After some more research, it looks like the problem is that the monitor is not giving the correct EDID information. I still haven't found a solution.
When i tried nouveau/kms for the first time, my screen went blank too.
I hadn't enabled "FIRMWARE_EDID" option because the description says
that it is needed if DDC/I2C doesn't work, so i thought it is not needed.
But the screen works only with this option enabled.
The cause in your case might be different, but check if FIRMWARE_EDID
is enabled in your .config.

Yes it is. .config I forgot to include it in the original post
