Good work! 1) How did you compile it and what did you change in Irrlicht's initialization code to make it work? 2) When you say started through Easy Debian, do you mean by using the nested X server Xephyr that running it through the "Debian LXDE" icon in the applications menu makes or by invoking it directly in the debian chroot via xterm (debbie ~/path/to/minetest/bin/minetest)?
