Any suggestions for how to do it properly?

ioremap ? :-)

Does ioremap work that early?

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.
