We need to know that in any case. The difference is that in the kernel 
case, adding support for new hotkeys requires upgrading the kernel. In 
the case of it adding a new button type that hasn't been seen before, it 
also requires upgrading userspace. If we do it all in userspace, we only 
have one application to fix up in most cases.

In the Windows world, vendors can provide customised distributions on a 
per-laptop basis. That's not practical in the Linux world.
