Yeah, that was the key-paragraph! I read this already in UPGRADING but obviously didn't understand it fully... 'portupgrade -af' is not an option here because of my ISDN-Line (64 kbit/s).

So that's the "show-stopper" for the nvidia-driver - at least for me for the near future until it works with 'libpthread'.
