Picking xset from the x11-xserver-utils package might be a plan, but
that one is linked against libXmuu.so.1 which isn't provided by any
udebs. It appears there are only two XmuPrintDefaultErrorMessage()
calls in xset/xset.c, which you can patch out, leading you to an
xset (ELF) binary you could include in your images.

I'm attaching a patch to that effect, recipe:
  apt-get source x11-xserver-utils
  # apply patch, install b-deps as needed
  cd xset
  autoreconf -vfi
  ./configure
  make

I haven't checked what happens in a d-i environment with the
resulting xset program, but you should be able to try:
  ./xset dpms force on

after having pulled it there.

Mraw,
