The kernel and user space fixes addressed the same technical problem
(failing to note that mode setting turned on the devices), but the
symptoms that this caused were different; in kernel mode, the result
would be that monitors would be left turned on when user space asked
that they be turned off (and left pointing at random memory too, which
was amusing). I think that the backlight issue was caused by the
user-space bug though.
