And after a bit more of digging, I couldn't find any documented setting 
for the gretter to enable that option... gee, the old GDM2 was -by far- 
more user-friendly and more easy to tweak :-/

I remember I had to do something similar to what you are seeking for 
enabling the touchpad "tap" action at GDM3 but IIRC (I'm not in front of 
my netbook where I have Wheezy with GDM3 installed) I had to edit one of 
the Xorg configuration files that I had to copy from "/usr/share/X11..." 
to "/etc/X11/xorg.conf.d/synapctic.conf" (or something like that) and 
then add a line to enable tapping at the login screen (don't ask me for 
the exact key, I don't remember...).

So maybe you can do the same for the "ctrl:swapcaps" by editing the 
keyboard configuration file (it must be under /etc/X11/xorg.conf.d/
*edev.conf) and put the option there, inside the keyboard input class, 
which, speaking from memory, it should be similar to:

Section InputClass
... keyboard stanza
... more options
Option "XkbOptions" "ctrl:swapcaps"
EndSection

And relogin to check. 

I can't test it right now but this worked fine at least to enable the 
tapping.
