This is wrong.  You need to pass either "stack" or "&stack[0]" as the
last parameter.

If that doesn't help, please post a short complete test program that
can be compiled and used to find out what's wrong.

No, 4 is not entirely correct, since "pop dx" only takes 2 bytes (but
I don't think this should matter in your case).

I would really advise to read the relevant parts of the DPMI spec if
you want to mess with low-level stuff like this.  Every `__dpmi_xxx'
function has its corresponding DPMI call that is described in the spec
with much more detail.
