Additionally, you probably want to consider the suspend2 kernel patch series from http://www.suspend2.net/ to allow for reliably shutting the system off without losing state and storing memory into your swap partition or a file.Has nothing to do at all with suspend to ram and the power consumption when suspended.I'm not sure you are right with that claim. There may be some code onto suspend2 patches that may help improve suspend/resume devices that are not yet merged to mainline. I don't think however this fill fix the thinkpad problem of the OP though.
See "S3: high power consumption - Thinkpad T40/T41" http://bugme.osdl.org/show_bug.cgi?id=3022 They have a patch that applies to the mainline kernel and fixes the problem. It is a video problem. If the patch doesn't work immediatly for you, you might have to add video=radeonfb:force_sleep=1 to the kernel command line and then add your machine's dmi data to the whitelist. The whitelist is pretty big by now, though, so you may already be covered. --Vernon
It's actually more or less a guess since I have not looked actually to the suspend2 code.
