            Hello,

Anybody know the reason RedHat decided not to support the
VIA Eden Processor?

          Possibly ... Does that processor have PAE?  The non-PAE kernel was
dropped, the current 'normal' kernel requires a PAE-capable processor.

My understanding is that this CPU is not even completely i686 compatible
... does CentOS-5 even work with that?

I thought that VIA Eden required i586 kernel and i386 or i586 glibc ...

(this may be a newer version than the one I tested 4-5 years ago)

    It has been running 5.x just fine. It also runs the ayplus kernel
    fine too:
