>Description:
running X results in a blank screen. No pointer is drawn this happens with both 
a DRM enabled kernel and a non enabled kernel.

The full X log is available at http://fishladder.co.uk/Xorg.0.log

Also on the console (with DRM kernel) i get 

error: [drm:pid14383: i915_initialize] *ERROR* can not ioremap virtual address 
for ring buffer

X seems to fail because it cannot initialise DMA.
>How-To-Repeat:
Configure X and run X with that config file.
