There is nothing wrong with that; I do it all the time.

You must edit another Makefile to specify your cross-compiler,
arch/ppc/boot/Makefile I think.

Those messages (unfortunately omitted here, but I think I remember them...)
looked simply like a failed tftp attempt, which is not vmlinux's fault. Of
course a vmlinux is much larger than a zImage, which greatly increases the
chance of an ARP timeout on the host (and ARP requests greatly confuse
RS/6000 firmware when they occur mid-tftp).
