I'm using wmlaptop from the control line. At present I get an error message but it works, and if you do it as user it vanishes along with the terminal when you exit. It's not well designed as a fixture as it hogs 64 pixels on the LHS of the screen and won't let any other windows into that strip, so don't try it as root - it won't go away. Not as good as klaptop in KDE 3.5 though.
