The default kernel commandline in the PReP kernel includes "root=/dev/sda2". Please remove this.
Well, this was selected because it is the default from arch/ppc/Kconfig. While it is not the ideal solution, I think it should stay enabled for the time being, because it can easily be replaced by running
perl -pi -e s+/dev/sda2+/dev/foo7+ vmlinuz
on the kernel image.
Sounds like that perl command being run by mkvmlinuz, supplying the current partition mounted on / . That shouldn't be too hard right?
