 On my box (8.04.2):
~$ ls -l /lib/modules/2.6.24-24-generic/kernel/drivers/ieee1394/raw1394.ko
-rw-r--r-- 1 root root 35764 2009-03-25 17:34 /lib/modules/2.6.24-24-
generic/kernel/drivers/ieee1394/raw1394.ko
~$ ls -l /usr/lib/libraw1394.so.8.2.0
-rw-r--r-- 1 root root 19964 2007-11-10 22:12 /usr/lib/libraw1394.so.8.2.0

So, they are not in my group, I don't need any special permissions and 
for me kino works. I think the only thing you really need is the read 
permission for others, the last r . The w for user root is there to make 
it possible for root to install and remove these files. I wonder if 
raw1394.ko (a kernel module) is loaded with your kernel. Do:

"lsmod | grep 1394" to see if something is loaded. For me (with kino 
started) it shows ohci1394 and ieee1394, no raw1394. You could also look 
at /usr/share/doc/libraw1394-8/README for more information.
