Yeah, I have done this in the past somehow with that kind of cleverness, but it looks like the fancy new three-operand ORG instruction is intended for exactly this problem.
(*+7)/8 can't be right -- you are dividing * by 8 which can't be right -- but yes, I get the idea.

If I mess it up let me know and I'll pull one tomorrow from a listing. IIRC something like org (*+7)/8 will do it.
