I have been trying to install Linux/GNU on an POwer Macintosh G3, but it
appears that this is not going to work.  Inserting a Yellowdog 3.0.1
install 1 CD-rom into the drive freezes the machine solid.  BootX versions
later than BootX_1.1.3 won't unpack.  BootX 1.1.3 freezes the machine about
60% of the time rather than starting a kernel.  rocklinux gets a CRC error
on the ramdisk and then can't find init.  ubuntu manages to continue after
ramdisk unpacking errors, and even goes as far as partitioning if you
restrict the partitions to 13 GB or less, but then it say it can't find the
CD_ROM it just has read lots of files from.

So, since there is no native platform I can test, would you like me to
benchmark cross-compiling a suitable package?  IIRC powerpc-eabisim is
a possible cross target.  Would CSIBE cross-compile time measurements
fit your requirements?
