I just tried booting kernel.bin on the NSLU2, as a raw memory image, via
tftp, and got exactly the same result.
I repeated it with U-Boot. It appears as though it relocates the
embedded ELF image to the correct address during load and execution, but
I can't be sure because I don't have any OCD capability just now.
Again, the hang happens right after init_turnstile0() appears to have
been called:

It also looks as though the DDB symbol lookup isn't working. The dynamic
symbol table is present in the ELF image. mkimage simply wraps the ELF
image with a U-Boot header.
