No, it only needs to be a < 4 MB raw partition of type 0x41.

No, wait... we really want to use yaboot.
I used to dd the kernel on my B50 but had to stop after upgrading to 2.6
because newer kernels cannot be loaded without a boot loader.
And anyway yaboot is needed to be able to choose among different
kernels, easily add command line options and so on.
To install yaboot /usr/lib/yaboot/yaboot must be prepared with
/usr/lib/yaboot/addnote and then copied to the PReP partition.
yaboot is able to load plain zImage kernels.
Do not count on ybin to work...

On my systems I use this instead:
setenv boot-device /pci@80000000/scsi@10/sd@2:
I think that OF will automatically look for the boot partition this way.
