Run X on a free virtual terminal, then you'll start fvwm and, say,
xterm on that:

E.g.:

$ sudo /usr/lib/xorg/Xorg -nolisten tcp -auth $HOME/fvwm-trial.auth :2 vt09
$ DISPLAY=:2
$ fvwm&
$ xterm&

That will start an X server on vt9 with display identity :2, with fvwm
and an xterm. Shift to it with C-A-F9 and shift back with C-A-F7.
