i've double-checked that there are no other video drivers affected by 
this problem:

 $ cd drivers/media/
 $ grep -C 10 videobuf_mmap_setup `grep -l mutex_lock */*.c */*/*.c */*/*/*.c`

 video/videobuf-core.c-  mutex_lock(&q->lock);
 video/videobuf-core.c-  mutex_lock(&q->lock);
 video/bt8xx/bttv-driver.c-              mutex_lock(&fh->cap.lock);

so only bttv-driver.c was affected, at first sight.
