They should be mapped into PCI address space with the rest, you should
note though that a bunch of people have asked this a bunch of times and
the response is usually null.
If you want to output debugging info, try a serial port, or if you're
still at the point in boot where the OF is still around, you can still
output to it (check prom_init.c) and if not, the open firmware
framebuffer console driver is your best friend..

Unfortunately unless you are running some kind of yaboot-accessible or
firmware-accessible x86 BIOS emulation, this isn't possible.
