Argument %0 is your length counter, not the destination selector.

Don't you mean to say movl? I'm surprised this even assembles...

But why are you wasting so much time on writing this routine, when 
movedata() already does what you need? I think it is crazy to make 
your own version of something that already exists, especially for 
such a simple routine where there is no possible way that you could 
ever make it more efficient than the libc routine. Look at the 
source if you are in any doubt (djgpp/src/libc/pc_hw/mem/md.S).
