I have seen it too on my lenovo T60 with 2.6.32.2. It happens to me
frequently and has become famous as "coffee bug" in my colleagues.
Every morning when I goto office and after putting my laptop on
docking station go for coffee. Once I come back the laptop screen goes
blank, but haven't been able to manage how to get screen back. Only
option is hard reboot. This happens almost every once in two three
days.

Let me know what information/logs I can provide to help debug this.
BTW I normally suspend my laptop at home and then resume it in office
(if that matters).
