Read that as "are capable of using" rather than "should use" and it
makes more sense.

Yes, you do. The 2005.1-r1 LiveCD only ships with a generic x86 stage3
tarball. There are two good reasons for this:
1) It simplifies the job of release engineering considerably.
2) The most broadly distributed packages CD featured binary packages
which are (and always have been) built in the same manner - that is,
with CHOST="i386-pc-linux-gnu" and -mcpu=i686. Thus you get packages
which are optimised for the i686 family of processors in general but
which will run on >=i386 processor. People were all too often mixing
the wrong stageball with said packages and running into compilation
issues further down the line.
Here are three plausible solutions:
Solution 1) Accept it and go with the flow. You can still set
CFLAGS/CXXFLAGS any which way you like ("-march=pentium4" for
example). The most obvious drawback when using this stageball is that
you can't build glibc with NPTL support ... assuming that matters to
you. It really isn't a big deal apart from that.
Solution 2) Don't use the supplied stageball and instead download
another one from a mirror using wget or whatever. The most "optimal"
choice for you is:
releases/x86/2005.1-r1/stages/pentium4/stage3-pentium4-2005.1-r1.tar.bz2
Solution 3) If you're very experienced with gentoo installation
procedure then you could perform a stage1 type installation (i.e.
bootstrap.sh to get to stage2, then emerge -e system to get to
stage3). Yes, you can do this even if you begin with a stage3 tarball.
