I think it might be the same issue that makes OSS crash on reload.
It loads itself under several names (all driver modules are linked into
a single binary for now), and I suspect final unloading doesn't clean
up everything... might leave things with globals left to their last
state instead of reinitializing them or something...
Should try to write a test module and see.
