No, I think you're way makes more sense as it may allow it to work correctly
with BASIC still banked in, or possibly on a 16k machine.  The crt0.s on the
Atari dynamically allocated the stack, or at least used to the last time I
looked at it.  That said though, must Atari folks know to press OPTION while
booting and also have full memory configs (often much more... 1MB is pretty
common now.)
