+ 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.
