how to start services in early stage of beaglebone boot

I am trying to change the Beaglebone black splash screen.

I flashed the BBB Sd card using Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.12-beaglebone-2013.06.20.img.xz image. Then I compiled the psplash source (as explained in!msg/beagleboard/HRDjAtsPO68/dc7gIZTynQkJ) and now psplash works fine.In order to automatically start psplash I create a new system service called psplash.service and I enabled it by the command “systemctl enable psplash.service”.

The problem is: when Beaglebone boots, the psplash is launched a little bit late and you can see for several seconds the standard beaglebone logo. How can I configure the service in order to run the psplash as soon as possible ? There is a better way than the system services for starting psplash program ?

Here is the system service file:

Description=Splash screen
