Hmm, don't have an AMD64 yet (waiting for the first dual-core laptop to 
become available!), but this certainly sounds like a 32-bit vs 64-bit 
library issue.

Take a look at /etc/ld.so.conf.  This file defines the library search 
path for your system, and ldconfig takes this file and generates 
/etc/ld.so.cache from it.  I suspect removing the entries for the 32-bit 
library directories, or possibly just moving them to the end of the 
list, would solve the problem for the majority of the programs.  You may 
run into trouble with some closed source 32-bit stuff though.  (VMWare, 
Adobe Acrobat, etc)
