           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
-	  directive, use either
-
-	       install firewire-ohci /bin/true
-	  or
-	       install ohci1394 /bin/true
-
-	  and so on, depending on which modules you DON't want to have
-	  auto-loaded.
+	  you are doing.
 
 config FIREWIRE_OHCI
 	tristate "Support for OHCI FireWire host controllers"
···
 
           NOTE:
 
-	  If you also build ohci1394 of the classic stack, blacklist either
-	  ohci1394 or firewire-ohci to let hotplug load only the desired driver.
+	  You should only build ohci1394 or firewire-ohci, but not both.
+	  If you nevertheless want to install both, you should configure them
+	  only as modules and blacklist the driver(s) which you don't want to
+	  have auto-loaded.  Add either
+
+	      blacklist firewire-ohci
+	  or
+	      blacklist ohci1394
+	      blacklist video1394
+	      blacklist dv1394
+
+	  to /etc/modprobe.conf or /etc/modprobe.d/* and update modprobe.conf
+	  depending on your distribution.  The latter two modules should be
+	  blacklisted together with ohci1394 because they depend on ohci1394.
+
+	  If you have an old modprobe which doesn't implement the blacklist
+	  directive, use "install modulename /bin/true" for the modules to be
+	  blacklisted.
 
 config FIREWIRE_SBP2
 	tristate "Support for storage devices (SBP-2 protocol driver)"
···
 
 	  You should also enable support for disks, CD-ROMs, etc. in the SCSI
 	  configuration section.

-          NOTE:
-
-	  If you also build sbp2 of the classic stack, blacklist either sbp2
-	  or firewire-sbp2 to let hotplug load only the desired driver.
