In fact, Mr. Branden kindly did this already for xdm :)

the file /etc/X11/xdm/Xservers included in xdm_3.3.6-9.deb does have
the line:

    :0 local /usr/bin/X11/X vt7 -deferglyphs 16

so "-deferglyphs 16" is used as the default for xdm.

Unfortunately, it seems that "startx" command currently does not 
have this setup as the default.

I think that providing /etc/X11/xinit/xserverrc by xbase-client
package can do this, because the current /usr/X11R6/bin/startx
has the following lines:

   userclientrc=$HOME/.xinitrc
   userserverrc=$HOME/.xserverrc
   sysclientrc=/usr/X11R6/lib/X11/xinit/xinitrc
   sysserverrc=/usr/X11R6/lib/X11/xinit/xserverrc
   clientargs=""
   serverargs=""

(snip)

   if [ -f $userserverrc ]; then
       serverargs=$userserverrc
   else if [ -f $sysserverrc ]; then
       serverargs=$sysserverrc
   fi
   fi

So I think that put the line similar to /etc/X11/xdm/Xservers
(maybe "exec /usr/bin/X11/X :0 vt7 -deferglyphs 16 ")
into /etc/X11/xinit/xserverrc will work as the default setting
for "startx" command.

Regards.
