I don't remember the specifics in detail, but I know it involves DKMS at some stage. I wouldn't necessarily expect it to happen even with the "rebuild module on package update" model used with DKMS, but as I said, I know I've *seen* it happen - with VirtualBox, quite some years ago now. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
