Ok, seems I should have lisened to Gerd Knorr and Ralph Metzler in the first
place.

I've tried to port the dvb-bt driver to the new sub device interface. It might
or might not work, depending on my luck :) You will need a snapshot of the
bttv core from http://cvs.bytesex.org/video4linux.html, at least from
2004-07-22 15:54. I have no idea what other (if any) patches you would need
except this one, so please enlighten me.
Note: You must reverse the patch I sent earlier, before applying this.
