Yes, without this option, the code bit-rotted horribly.  It needs to be
able to be built otherwise people will change the code and it will break
and no one will notice except Guenter's build bots and then no one will
fix it :(

i.e. exactly what was happening before...

So this needs to all be fixed up properly, and really, should be merged
to the "real" part of the kernel...
