The evidence is compelling. there's one possible solution to this, and I seem to remember that at some time some variant of (MS/DR/NOVELL/...)DOS had the following solution: look at first few instructions in program (or typical header values etc.) if this looks like a brain dead old exepacker, relocate it above 64K; i.e. do an automatic LOADFIX. shouldn't be a big problem to implement.
