I re-built last night and the eMac hangs in the ATA probe, so you're a
little better off than I am :) Working on it as we speak.

When booting the loader from the OpenFirmware prompt, give it a
partition which is either non-existent, doesn't have a kernel to load,
or isn't a UFS partition e.g.
0 > boot hd:loader hd:0
can't load kernel
Type '?' for a list of commands, 'help' for more detailed help.
At this point, you can set currdev and manually load a kernel e.g.
OK set currdev=hd:14
OK load /boot/kernel/kernel.save
