I've reported this before:
http://lkml.org/lkml/2004/11/17/275
The patch that Rusty posted doesn't seem to have it made into
module-init-tools-3.1. Bummer :-(
The Bug in saa7134-core.c doesn't seem to have been addressed yet, so
I suggest the following patch as a temporary measure:
--- linux-2.6.10/drivers/media/video/saa7134/saa7134-core.c.orig 2004-12-25 19:22:55.000000000 +0100
