I marked this bug as verification failed because scrolling, while
working after boot, breaks after suspend/resume.  Do you want to ship
the current fix and address suspend/resume separately?  This should
alleviate a lot of pain for users (and users of the Bluetooth version
won't see the suspend/resume problem because it has to reconnect).

The workaround with the patch applied it to unplug the cable from the
keyboard and plug it back in again.  Certainly better than no scroll at
all for right now.
