ieee1394 patch

I am a member of the Linux 1394 team, and I have been improving hotplug
capabilities of various ieee1394 modules. Below is my patch to the agent
script. For two different classes of video camera, some applications
require 2 modules: one for the control protocol and another for the
streaming video. Therefore, you see I removed that break. Also, I added
support for a module-specific script directory. This is especially
useful for sbp2 to invoke the popular rescan-scsi-bus.sh script, 
/etc/hotplug/ieee1394/sbp2 script:

#!/bin/bash
if [ "${ACTION}" = "add" ]; then
	. rescan-scsi-bus.sh
else
	. rescan-scsi-bus.sh -r
fi

Similarly, a dv1394 script could launch Kino on add, and a video1394
script could launch Coriander on add.

Make sure this doesn't run on 2.5.x. We have scsi hotplug there.

Good point. This is mostly an example of my personal configuration. It
should be easy to add sed against uname or /proc/version to check the
kernel version for a generic script.

Merged.  Your other patch was already in CVS; were you not
using the repository at SourceForge?
