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:



   if [ -f $userserverrc ]; then
   else if [ -f $sysserverrc ]; then

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.
