That's why I suggested moving it to drivers/staging - it's a hint that
the driver needs a serious amount of work, and when built as a module,
it also provides users with the hint that the module they're loading is
of questionable quality (which is definitely the case here.)

Others have done that kind of thing before - we've had drivers which
have fallen by the way side, and at some point the decision has been
made to move them to drivers/staging, and if nothing happens to fix
them up (showing that no one cares about them), they've eventually
been dropped.

Of course, us talking about this might be enough to spur some effort
to get the thing properly fixed. :)
