Well, my "OK" is of both kinds. 8-)

I've successfully converted ELF64 Linux images to o32 ELF32, with
`objcopy' and then to COFF even, with `elf2ecoff' (provided with the Linux
sources). The resulting COFF image used to work with the DECstation's
firmware. I suppose the intermediate ELF32 one would work with
ELF-capable firmware, too. Of course I had to make sure the addresses
seen by the firmware in the file headers fit the 32-bit address space
(KSEG0, actually; KSEG1 might work, too).
