You're trying something really tricky. If there's any chance of it working I guess you could try identifying at what address a module is loaded with "
mem /c" and then "mem /m:---" with the name of the module. Add /p if info doesn't fit a single screen page.
I'm not sure it's possible at all, as far as I know emm386 changes the whole memory model and address space, as well as where other stuff is loaded, and was famous to cause all kind of incompatibilities.
To get around these compatibility issues you could also try a different, 3rd party expanded memory driver, such as
QEMM.
EDIT or jemm386 as Zirkoni says, I don't know them all.
