I tried pRamdisk for ppc_4xxFP and ppc_4xx. I am not sure of the difference between ppc_4xxFP and ppc_4xx. But just a heads up. With ppc_4xxFP, I get the same results as for the
ppc_4xxFP is for PPC 4xx processors with floating point unit; your processor belongs not to this group.
All this is documented - please see the DULG (to be more precise, see the table at end of section 3.5 at http://www.denx.de/twiki/bin/view/DULG/ELDKUsage
With ppc_4xx, I get these messages

Well, and which results did you get when decoding this call backtrace?
I also have a question concerning Linux debugging with abatron. I can set an instruction breakpoint (e.g at start_here in the kernel) when I use a zImage.elf image but
zImage.elf is definitely not what you want to use. You have to use the vmlinux file in the kernel's top level directory.
the same breakpoint doesnt work when I use u-boot to boot vmlinux.PPCBoot image.
