I did write a patch to introduce a black list for such devices ;-)

Seriously. The kernel can learn to deal with broken devices on its own.
It's a question of black listing or introducing workarounds. Cumbersome
but doable. The question of whether to charge a battery in a device or
conserve the laptop's batteries is not solvable in the kernel. How would
you decide?
