[Bug 440411] Re: spam of change events from drm/card0

[Slavius]

Personally I don't think this is going to be 100% resolved because I've
noticed very similar behavior in Windows on the same box too. I've been
testing this for a long time and it seems that after I boot up Windows
remaining time of the battery shows around 5h. Then I do some heavy
graphical processing (watching flash video, enabling and using Aero) and
the battery life suddenly drops to  around 2h. This state persist until
the battery is completely drained. It looks like an Intel firmware bug
to me and all effort to solve this on the Linux kernel side will be more
or less a hack/workaround...
