Yes, I have have heard about the question of whether Biewers have Irish spotting (si) or piebald spotting (sp). They are both different mutations in the same gene. I can't answer that question based on appearance, because I've seen a broad range of degree of spotting in Biewers--some look Irish, and some look more piebald. Supposedly, the piebald gives more variation in the different patterns you see, so that's why I was guessing that Biewers are piebald, but hopefully the testing company will be able to answer the question for certain.
