I think the library copying technique should work if your distribution's 
libraries are built for i386 architecture.  I have used Redhat and 
Slackware and I believe they both have i386 libraries.  Redhat has i686 
libraries as well, but they are in a separate /lib/i686 directory.  If 
you want to be absolutely sure that your libraries are compatible with 
your architecture you can build them from source.  It really isn't any 
harder than building any other package, but it sure takes a long time.

If you want to build the libraries (or any of the other basic packages) 
I have a project called "The GNU/Linux System Architect" that can 
automate the building tasks.  Basically you type 'architect glibc-2.3.2' 
and after some time you get a binary package called 
'glibc-2.3.2.i386.tar.gz'.  It also builds many other system packages. 
You can get Architect at SourceForge.  The home page is 
http://architect.sourceforge.net.

Good luck building your laptop.
