I'm using floppy images available at
http://archive.debian.org/debian/dists/woody/main/disks-powerpc/current/prep/images-1.44/
more specifically root.bin
The default cpu has already been changed once between 0.11 and 0.12, so 
I think it's not impossible to change it once more.
Moreover, I don't think prep emulation is used in any production 
environment...

It seems that 'prep' emulates a Motorola, maybe the 
PowerStack/BlackHack, but I'm not sure...

With 601, Open Hack'Ware doesn't work.
With 602, the Debian installer doesn't start.
With 603, the Debian installer starts.
With 604, Open Hack'Ware doesn't work.

Will you accept a patch to change '602' to '603'?
