I already have a fix for this, but as-per my earlier suggestions I'd like to start discussing non-trivial freeze changes before making them. In frozen I'd just change boot-9.scm to check for the zero? case. That way we're guaranteed not to affect any other intenal code that might depends on the particular quirks of integer-expt in numbers.c For unstable, I'd go ahead and fix integer-expt directly, but not immediately. I've been working on the issues involved in using gmp with guile, and I'd probably just handle it during that process.
