because distros choose not to support it.  in first gen chips, there was 
hardware support for running x86.  so if we were to be strict, there should 
have been /libia64/ (or whatever) while the current x86 32bit code would stay 
in /lib/.  but no distro was interested in supporting that (probably due to 
the 32bit x86 layers being balls-ass slow), so it never happened.

i always thought this was weird.  glad to know i'm not the only one :).
