Works fine. Only problem is that it is dependent on "find", while the default version of find on the N900 is the busybox built-in. Install the GNU find, (apt-get install findutils-gnu), remove the symlink to busybox for find, "rm /usr/bin/find", create a symlink to GNU find ("ln -s /usr/bin/gnu/find /usr/bin/find"), run "/usr/bin/gnu/updatedb" to build the locate database, now /usr/bin/gnu/locate will work.

If you want to uninstall GNU find for any reason, then delete the symlink to it you created ("rm /usr/bin/find") and create a new one pointing to busybox ("ln -s /bin/busybox /usr/bin/find").
