How often to we encounter code generation bugs which are specific to this

I'm quite open to the idea of building certain heavyweight package sets (GNOME,
KDE, OpenOffice.org, etc.) for i686 if there is a demonstrable performance
benefit.  I'm much less convinced about the idea of doing this universally,
especially considering thin client deployments.
