Yes, If you already have a custom init script (Which I believe is what loads displayserver), you could put the call to empanim in that same file. To see if you have a custom init, cat /bin/init. If it's legible text, then you can add empanim to it. Keep in mind that the last thing init does is start the player, so anything in the script will run before the player does.
