Current saa7134 driver breaks KNC One Tv-Station DVR (card=24)

[Bernhard Rosenkraenzer <bero@arklinux.org>]

Trying to modprobe saa7134 with this card results in a hanging modprobe 
process.

dmesg gets:
saa7130/34: v4l2 driver version 0.2.12 loaded

At that point, modprobe hangs; I can still use the box in other ttys, but [of 
course] the saa7134 card doesn't work.

This is reproducable at least with with 2.6.10-rc3-mm1, 2.6.10 and 2.6.10-ac1; 
the card used to work with earlier releases (I can't remember the last 
version that worked though, haven't used it for a while).
