Yes, I think this should work:

Download files draw.lisp, grcommon.lisp and vtk.lisp from the Maxima
repository (folder share/draw) and place them somewhere in your user
tree.

Change lines 34 and 35 from draw.lisp to something similar to 

($load "path_to/grcommon.lisp")
($load "path_to/vtk.lisp")


Then, every time you need to draw something, write

load("path_to/draw.lisp") $

and you are done. If you want to play with the vtk renderer,

sudo apt-get install vtk

and you are done.

Let me know if it doesn't work.
