Public bug reported:
On Thinkpad R50e. Boot normally, get to your desktop and run powertop,
you'll see acpi as the top cause for wakeups (30~60), now unload
thinkpad-acpi *and reload it*. acpi won't do more than a few wakeups.
Notice that after you unload the module you will loose functionality so
blacklisting it is no option, also the unloading+loading is enough to
get acpi out of the causes for wakeups.
This is a serious issue, since wakeups go from around 150 to 70~80 after
doing this.
I tried adding a rmmod+modprobe in rc.local but seems that it's too early to
work... maybe it's related to gnome-power-manager? I can't imagine
gnome-session or gnome-panel are polling acpi so much that it wake ups so often.
Still, killing it and running it again after "fixing" the issue does not cause
any problem.

thinkpad-acpi makes acpi produce lots of wakeups, unloading and reloading
solves it
