-comment "Texas Instruments PCILynx requires I2C"
+	  You should only build either ohci1394 or the new firewire-ohci driver,
+	  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.
