What exactly is causing anything lower than i686 to fail ? If it is 
anaconda, CentOS could patch it slightly. If it is the kernel, we could 
build a i386 one ?

Not sure if we want to do this. What are the arguments for and against 
this ? I do see some benefit to have RHEL2.1 and even RHEL3 to work on < i686.
