So I turned to the /root/hda-install.log and found a number of errors. Now this was a fresh Express CD headless install; No updates or changes had been made. I stumbled into a forum thread that suggested a downgrade option on an unrelated issue. I ran the suggested: yum downgrade hda-platform command and tada... Amahi installed and booted successfully.
I'm all about supporting development, but the latest "stable" version needs to go back to beta in my opinion. I should add that this was after I had attempted installing FC12 by itself and then the latest "stable" Amahi. That failed with similar results.
