There was no message about missing file. But I didn't put any addition line
inside the modules.list entry. I don't know whether this is the cause of
the problem.

But, wait...

When I tried to insmod hello.ko, I got error message: Invalid module format
So btw, if my kernel module has been placed inside the Ramdisk, I don't
need to use the l4bdds? Because I just followed the instruction before and
don't know what to do with that kernel module file.
