the bootstrap partition will not inerfere with yaboot on the hfs
partition, you just need to boot into OF and run the following
command:

boot hd:X,yaboot

where X is the partition number of your HFS partition.  unless you are
using yaboot 0.5 it will work, ive done it.  0.4 was broken and almost
always failed to find its config file.  (i think pretty much any time
there was more then 1 or 2 partitions on the disk, and always on scsi)

if your macos partition is HFS not plus then:

mount -t hfs /dev/hdaX /mnt

and get the tarball from theere (if you downloaded to macos)

otherwise i suggest setting up network access and downloading it.

it won't work, its not a ybin issue its, an OF issue, OF uses the first
partition it finds a bootable file on, if that is macos then your
screwed.  this is why you must have the bootstrap partition be first,
so once its setup you never have to worry about OF again.  but until
its setup OF will ignore it. so your problem now with yaboot is
certainly not the bootstrap partition but either 1) yaboot 0.4 or 2)
bad yaboot.conf or 3) a new yaboot bug im not aware of. or 4) bad OF
boot command.

im working with Dan to get ybin on the boot floppies and in the base
system so this will no longer be an issue. hopefully we will be able
to automate this setup in dbootstrap, ybin 0.11 should facilitate that
end. 

also note i released ybin 0.11 which supports command line options and
limited autogeneration of a yaboot.conf file.
