I think the g++ is the problem, but I'm not sure what it is.

The driver is mostly a wrapper around a generic driver released by the
manufacturer, and that's written in C++. But it worked like this for the
2.4.x kernel series, so I think it has something todo with the new
module loader code. Possibly ld misses something when linking the object
specific stuff like constructors?

I don't think there are any other errors in the module (like
incompatible MODULE_stuff or missing statements), as it has been copied
from a patched alsa-0.9.6, and I diff'd the other drivers, not finding
much differences (if any).

Any ld parameters I could try? I already tried -Ur, but that lead to
nothing :(

thanks,
Lars
