resume from suspend do not work with thinkpad R61i (freeze and crash)

[suokunlong]

Steps to reproduce:
1. click "suspend" (top-right of the desktop area)
2. resume from suspend.

Current behaviour:
I can only see my mouse icon on the desktop; then xorg seems freezed and crashed. I have to reset my pc.

Further steps:
3. in terminal, execute "sudo pm-suspend".
4. resume from suspend.

Current behaviour:
The desktop appears but freezes.

In fact suspend never worked since ubuntu 13.10 in my Thinkpad R61i. (please note that suspend works ok in Fedora 20 with my pc)
