-          IEEE 1394 describes a high performance serial bus, which is also
-          known as FireWire(tm) or i.Link(tm) and is used for connecting all
-          sorts of devices (most notably digital video cameras) to your
-          computer.
-
-          If you have FireWire hardware and want to use it, say Y here.  This
-          is the core support only, you will also need to select a driver for
-          your IEEE 1394 adapter.

+          This is the "Juju" FireWire stack, a new alternative implementation
           designed for robustness and simplicity.  You can build either this
           stack, or the classic stack (the ieee1394 driver, ohci1394 etc.)
           or both.
 
+          To compile this driver as a module, say M here: the module will be
+          called firewire-core.  It functionally replaces ieee1394, raw1394,
+          and video1394.
+
+          NOTE:
+
+          You should only build ONE of the stacks, unless you REALLY know what
+          you are doing.  If you install both, you should configure them only as
+          modules rather than link them statically, and you should blacklist one
+          of the concurrent low-level drivers in /etc/modprobe.conf.  Add either
+
+              blacklist firewire-ohci
+          or
+              blacklist ohci1394
+
+          there depending on which driver you DON'T want to have auto-loaded.
+          You can optionally do the same with the other IEEE 1394/ FireWire
+          drivers.
+
+          If you have an old modprobe which doesn't implement the blacklist
