  FYI:  I looked into it in some depth once; it would require quite a hefty
bit of patching, since the information about symbol values isn't evaulated
yet at the time the parser is reading the MEMORY command.  See PR ld/518 
http://sourceware.org/bugzilla/show_bug.cgi?id=518, also see
http://sources.redhat.com/ml/binutils/2004-03/msg00540.html
for a detailed analysis, and 
http://sources.redhat.com/ml/binutils/2004-03/msg00571.html
for a suggested solution.

    cheers,
