Probably the easiest way around this problem would be to convert your 
image - either to Motorola S-records or pure binary.  RedBoot should 
then be able to load it (albeit maybe a bit slower) without problems.

  sh-elf-objcopy -O srec vmlinux vlinux.srec
-or-
  sh-elf-objcopy -O binary vmlinux vmlinux.bin
