PS1: 
Looking at the comments in `ebda.c`, using write_le16() is already
a hack to avoid compiler trouble or warnings. In theory we could
allow using these functions for fixed addresses (i.e. not only
pointers to objects in the program; what C expects). But I actually
like the warning as it kind of reminds us what this API should be
used for.
