For the raw1394 checkbox, versions before 0.3 just simply changed the
permissions line in /etc/udev/rules.d/40-permissions.rules to be part of the
"video" group rather than "disk", version 0.3 (or the 8.10 release) should
have done that plus add the raw1394 module (but I think a bug made it only
modprobe rather than change permissions too).  Versions 0.4 modprobes and
adds a line to /lib/udev/rules.d/50-udev-default.rules that gives
permissions to the "video" group (provided the latest bugfix is uploaded).

I hope that helps explain things - feel free to add this to a new
documentation page at
