Are you sure this isn't just some wackiness in the virtual 
memory reporting on amd64?   I've been using debian amd64 
for a while, and the VSZ numbers have been consistently absurd 
for all my processes (eg they often total to considerably more 
than my available RAM + swap).  For instance here's my emacs 
on debian woody (32bit):

       % emacs -nw &
       [1] 13029
       % ps u
       USER       PID %CPU %MEM   VSZ  RSS ...
       joe      13029  0.0  0.3  8020 3208 ...

and on amd64:

       % ps u
       USER       PID %CPU %MEM    VSZ   RSS ...
       joe      21248  0.0  0.2  29144  4336 ...

The libraries emacs links to are basically the same:

 % ldd `which emacs` | perl -alpe '$a += `du -bL $F[2]`} $_=$a;{'

 =>

   5060944 bytes for 64bit, 
   4063232 bytes for 32bit.

So the libraries are ~25% larger, the emacs binary
is ~60% larger (3985408 vs 6633208), but ps reports
almost a four-fold increase in VSZ.  Go figure.

Here's a possibly relevant link I found while googling
for an answer:
