Do you have a graphics device running?  Most of the ones I've looked at
have a call to R_open_driver(), or don't call G_gisinit() before
defining module options (bad).

Depending on the module, this shouldn't be too hard.  But, the module
must have a version in grass5/etc/bin/cmd/ otherwise the front end
intercepts the command line call with parameters (all that gmakelink5
line noise stuff).  There's nothing in the grass-interface.dtd to flag
an interactive or console-interactive module.  Perhaps such an addition
would be useful?  I just did such a thing with d.display, but I won't
commit it for the time being since the XML output isn't very useful (the
description from the "man" page).

Somebody must've thought so at one time ;)
