... is the message I get from QEMU's official ppc OpenBIOS blob. sparc and sparc64 blobs work better.
Probably the ppc blob just needs updating. My cross-compilation is still running to confirm whether HEAD works better.
Some notes: binutils 2.20.1 and 2.20 do not compile on Mac OS X v10.6. They error about lots of _("...") format strings that Ubuntu (gcc 4.4.1) just warns about. OSX default gcc is 4.2.1; CC=gcc-4.0 leads to /usr/lib/iconv.la not found during linking instead.
