Sorry, I don't understand: what pushing and popping?  All you need to
access a far pointer in assembly is to load FS with the _dos_ds
selector (once) and then use the fs: segment override.

You can leave that behind if you access the ``normal'' memory mapped
into your address space.  Accessing devices mapped into specific
absolute addresses is not something ``normal'' programs do.
