FWIW, my Toshiba Satellite P850 also works correctly with bbswitch
without having to use acpi-handle-hack with linux < 3.8.5.

Given that the need for acpi-handle-hack is the exception rather than
the rule, that it's an ugly workaround for something in the kernel (no
idea what this does to be honest, you'd have to ask upstream), and
that jessie is going to ship with linux >= 3.8.5 for sure anyways, I
probably wouldn't package acpi-handle-hack.
