I'm not sure AIX works on Macs. In fact, I'd even strongly believe that we're missing a _lot_ to make it actually work in qemu. There's probably subtleties in the cpu emulation code missing/wrong on top of RTAS not being there on top of us failing to even load a kernel. Patches are welcome, but I certainly won't look into AIX anytime soon.

*shrug* looks like OpenBIOS doesn't know how to deal with that usb controller. It's definitely not related :).
