Yes, this is a known problem. (It's described in the README file in the
top directory of the CDK.) The problem is that ptrace is not yet
implemented for the 4xx processors. I have ptrace working in an old
version of the kernel, but haven't yet moved it forward to a current
kernel and cleaned up the implementation. This is a very high priority
item for completion.
