It boils down to one thing - the installer needs to make a decision
based on the information it knows about and the information it can find
as to what is the best post-install kernel to leave as the default boot
kernel on the installed machine. ( phew, long sentence )
In this case, the CentOS installer is using the info it can gather and
making a ( perhaps wrong ) decision that it needs a i586 kernel. The
reason I say perhaps wrong decision is simple - The installer is built
with the lowest-common-known-to-boot-everywhere kernel that is available
in the distro. Since we only have i686 support, this kernel the
installer is running on itself is the i686 kernel. And if your machine
got to a point where its doing its thing, I'd say its a fair guess that
the i686 kernel is fine for that machine.
To further test this theory, boot the CentOS-5 installer into rescue
mode. Get to the shell, play around and do the same tests / enquiries
you just did. Come up with anything interesting ?

in this case, the fix is to have anaconda know about the hardware and
get the right ( i686 ) kernel for it. I believe Daniel has already
hinted that cpu/platform knowledge in the installer itself is going to
need some love for the i586 stuff to WorkAsDesired

awesome! Ray is already making some noise to get the project resources
allocated. Once something is up, make sure you sign up for punishment^W
