This commit makes suspend to ram unreliable for me:
commit d1b851fc0d105caa6b6e3e7c92d2987dfb52cbe0 Author: Zou Nan hai <nanhai.zou@intel.com> Date: Fri May 21 09:08:57 2010 +0800
drm/i915: implement BSD ring buffer V2
The BSD (bit stream decoder) ring is used for accessing the BSD engine which decodes video bitstream for H.264 and VC1 on G45+. It is asynchronous with the render ring and has access to separate parts of the GPU from it, though the render cache is coherent between the two.

git revert didn't work on 2.6.35-rc6 so I just changed the HAS_BSD thing to:
#define HAS_BSD(dev) (0)
with this change applied suspend to ram is back to the reliability of 2.6.34.y
with kind regards thomas
