Well, I though the syscall code got from

	code = frame->fixregs[0];

at line approx. powerpc/trap.c:174

That should at least tell if the syscall code matches getpid(2) or chown(2),
i.e. if the syscall number is passed correctly to kernel or not.

Well, if Linux used something like our SYS___syscall trick, the padding
might cause troubles if not properly handled theoretically.
