Ok, this instead of getting the wrong address, wine just bails out with:
wine: failed to create the process heap.  The other message still appears if 
the load address is high enough.

This is how I'm testing:
I've downloaded the August (20040813) version of wine applied the patch to 
comment out the reservation of the dos area in a previous email (attached 
again, idealy we shouldn't apply this since having the stock wine work would 
be much better), and did a ./configure && gmake depend && gmake && gmake 
install.  I've attached my wine config file.  Then I just end the 
environmental variable you said and run wine.  I'm using Diablo 2 as my test 
app.
