FWIW, 2.6.36-rc3-00396-gbe6200a suspend-to-ram works for me on GM45 (Dell E4300). I am running Ubuntu with xorg-edgers from a few months ago: xserver-xorg-core 2:1.6.5+git20091107+server-1.6-branch.2dbcb06a-0ubuntu0sarvatt~karmic xserver-xorg-video-intel 2:2.11.0+git20100415.c374c94e-0ubuntu0sarvatt~karmic There are several regression fixes pulled after 2.6.36-rc3 in merge commit 4eab8a5717f5, can you try current linux-2.6.git ? If it still fails, please post - lspci -vvv - /var/log/Xorg.0.log from after the failure - dmesg -andy
