Combining two drivers into a single kernel object certainly doesn't work
("multiple definition of `init_module'" error, etc).
Indeed, this changes the name of the driver. It should be fine as long
as it doesn't hurt anybody, so what about to keep this change as-is for
now and wait for complains? I promise to make a revert if this will
cause real problems for anyone. Let's be realistic, there should be a
very little chance that somebody will notice this change. ACK?
