Well, there will be several versions of the BIOS signature, which the
constructor is not likely to provide.

Just to make sure there's no misunderstanding: it was never planned that
this driver be loaded unless some manual intervention, like explicitly
loadling the module or setting some parameter, so that if bad effects
happen on the machine, the user can only get angry at himself for having
loaded by hand a random module without reading the documentation that
explicitly says (twice) it's only for a particular kind of hardware.

I however now realize that I don't find a way to force a driver to be
compiled only as a module.  If there isn't, I guess we can just add
a module parameter to enable/disable the driver, so that it won't be
active by default even compiled-in?
