It works very early on ppc32 but maybe not -that- early... It works from start_kernel on. You might be able to do the ioremaps in machine_init (provided LMBs are up) but they won't be "effective" until MMU_init returns, but then, neither will setbat anyway. However, since that's the only user of setbat I can still find and we want to replace that with something saner, I'd rather kill it.
