2.6.16-rc2 kernel oops when loading v4l-dvb bttv

FYI:
A few days ago I tried out 2.6.16-rc2 with v4l-dvb and I got a kernel oops.
I thought I mixed up some modules but today I tried again more carefully
and there is something wrong here. The modules as are part of 2.6.16-rc2
are fine, only if I recompile v4l-dvb for the 2.6.16-rc2 kernel and
install the new modules (first deleting the old ones), and then load
bttv I get kernel BUG message reproduced below.
Again, the bttv module from the 2.6.16-rc2 kernel is fine.
