If possible, yes, as this issue affects other laptop manufacturers,
we may never know if someone might try to load an older kernel
on an affected laptop and end up with the toshiba_wmi loaded
instead of the actual laptop support module, however, I'm not
sure if this is a "big" issue to bother stable, if not, simply drop
the cc to stable for me please.
