405 overlays

There is a little-known less-understood
feature for text overlays in the V7 kernel,
where an exec of a binary with a 405 magic
number will bring in a new text segment,
leaving the data segment alone.  You know,
`chain'.

Does anyone have a version of ld.c that
can make decent use of this facility,
or is there some tricky way to get
vanilla ld to do what you want?
