Based on Trygve advices i made a few tests and had a look to the way 
sun's gnome desktop is working.  I run a Ultra 20, thus an amd64 CPU. In 
the Solaris installation there is both 32 and 64 bits versions of pango. 
Here are the files i have :

64 bits version

[william at cyaegha:/usr/lib/amd64]$ ls *pango*
libpango-1.0.so          libpangoft2-1.0.so          
libpangox-1.0.so          libpangoxft-1.0.so
libpango-1.0.so.0        libpangoft2-1.0.so.0        
libpangox-1.0.so.0        libpangoxft-1.0.so.0
libpango-1.0.so.0.501.1  libpangoft2-1.0.so.0.501.1  
libpangox-1.0.so.0.501.1  libpangoxft-1.0.so.0.501.1

pango:
1.4.0

[william at cyaegha:/usr/lib/amd64]$ ls pango/1.4.0/modules/
pango-arabic-fc.so  pango-basic-fc.so  pango-basic-x.so  
pango-hangul-fc.so  pango-hebrew-fc.so  pango-indic-fc.so  pango-thai-fc.so

32 bits version

[william at cyaegha:/usr/lib]$ ls *pango*
libpango-1.0.so          libpangoft2-1.0.so          
libpangox-1.0.so          libpangoxft-1.0.so
libpango-1.0.so.0        libpangoft2-1.0.so.0        
libpangox-1.0.so.0        libpangoxft-1.0.so.0
libpango-1.0.so.0.501.1  libpangoft2-1.0.so.0.501.1  
libpangox-1.0.so.0.501.1  libpangoxft-1.0.so.0.501.1

pango:
1.4.0

[william at cyaegha:/usr/lib]$ ls pango/1.4.0/modules/
pango-arabic-fc.so  pango-basic-fc.so  pango-basic-x.so  
pango-hangul-fc.so  pango-hebrew-fc.so  pango-indic-fc.so  pango-thai-fc.so

By default /etc/pango/pango.modules contains the 32 bits modules, even 
on my amd64 version.

I made the following tests running both 32 bits and 64 bits version of 
gtk-demo (/usr/bin/gtk-demo and /usr/bin/amd64/gtk-demo).

. Running application gtk-demo and pango.modules using same versions 
(both 32 or both 64 bits) work is fine.

. Running 64bits apps with 32 bits modules works also, but running 32 
bits app with 64 bits modules does not work.

Please notice that from Sun's isntallation running both 64bits, or 
64bits apps with 32bits modules produce the same warnings

     (gtk-demo:19058): Gtk-WARNING **: Unable to locate theme engine in 
module_path: "blueprint",

Running a full 32bits stack produce no warnings



So i may suggest to do some more testing, like recompiling a couple of 
our desktop app in 64 bits mode, and test these apps against 32 bits 
modules. If it work fine, we may generate by default a pango.module 
config file containing 32 bits modules.

Because :

1/ it works :)

2/ most of the desktop app are compiled only in 32 bits

cheers
