FVWM: Resizing BarButtons based on display size

Hi all,

This is a bit of a silly question.  I have a FVWM config that's about 10
years old now that I set up to be largely keyboard oriented and maximise
screen real-estate.

For system status and a calendar, I have a BarButtons instance on the
right-hand side of the display which I can call up by hitting Logo, Z.
The problem is every time I've moved to a new machine, I have to edit
the config file to appropriately dimension the panel.

I want the panel to be the full height of the display, minus the height
of the task bar (now, fbpanel; since FVWM have dropped FVWMTaskBar).

Right now I have this:
> DestroyModuleConfig BarButtons: *
> *BarButtons: Fore Black
> *BarButtons: Back #cccccc
> *BarButtons: Font "xft:sans-serif:Bold:pixelsize=10;-*-helvetica-bold-r-*-*-10-*-*-*-*-*-*-*"
> # Geometry - really likes to pick its own size, but giving a position is OK
> # Warning: I've added a size geometry to avoid pbs if the fvwm_icons are
> # not in the image path ! Remove the size in this geometry especially if
> # you add buttons
> #*BarButtons: Geometry 250x568-0+24
> PipeRead "${HOME}/.fvwm/position-barbuttons.sh"

with the script containing this:
> #!/bin/sh
> 
> printf '*BarButtons: Geometry 250x%d-0+24\n' $(( \
> 	$( xdpyinfo | sed -ne \
> 		'/dimensions/ { s/^.*: \+[0-9]\+x\([0-9]\+\) .*$/\1/; p }' ) - 24 ))

This works, but I wonder if there's a more elegant way.  Is it possible
to grab the screen size in the .fvwmrc and do the required arithmetic
for deriving Geometry?
