NACK.
This hack is unacceptable. Uwe, Please have patience -- I have a few ideas on
how to do this without using #ifdef's , but I am spending my time on other
things right now. Trent also had some ideas on how remove the static
dependencies on dvb-pll, but we all have bigger fish to fry.
For the time being, you should use this on your own kernel configuration, but
this is not correct, and should not be pushed into mainline.
