You can always use NEI or CraftGuide to check recipes. Additionally all IC2 crafting recipes are in assets/ic2/config inside the jar:
IC2:blockMachine3@5 = "UBU|UMU|UCU" M:IC2:blockMachine U:IC2:upgradeModule@3 B:OreDict:circuitBasic C:minecraft:chest@*
IC2:upgradeModule@3 is the ejector upgrade
The configuration advice is exactly what I was looking for. Thanks!
