My fvwm2 setup is like that (the config line "DeskTopSize 3x3" does the trick) plus keybindings to jump the cursor a half or a whole screen so I don't usually need to touch the mouse while navigating around (focus follows mouse is essential to this).

I was thinking about switching to Ian Jackson's wm of choice, vtwm [1], but the fact that fvwm has even that it's incredible.

FVWM is truly the living bible of window management.
