Alternative packages are chosen based on the ALTERNATIVE_PRIORITY.  You have
given yours the same as psplash-angstrom. Increase your priority so it will
be the preferred alternative.

Additionally, you should look into amend.inc for cases such as this.  It
allows you to tweak recipes in your overlay without duplicating the entire
recipe.
