The problem was introduced by the following commit:
commit faee816b1502385dc9bc5abf2960d1cc645844d1 Author: Zhang Rui <rui.zhang@intel.com> Date: Fri Sep 12 11:12:25 2008 +0800

don't enable control method power button as wakeup device when Fixed Power button is used.

Reverting this commit on top of the current mainline makes the kernel behave correctly again.
Thanks, Rafael
