CentOS 5 x86_64 updates contains: etherboot-pxes-5.4.4-13.el5.centos.x86_64.rpm etherboot-roms-5.4.4-13.el5.centos.x86_64.rpm etherboot-roms-kvm-5.4.4-13.el5.centos.x86_64.rpm etherboot-zroms-5.4.4-13.el5.centos.x86_64.rpm etherboot-zroms-kvm-5.4.4-13.el5.centos.x86_64.rpm
This belongs to CEBA-2010:0227 and is x86_64 only. Neither CEBA-2010:0227 nor any of the above packages been announced.
There's also some more weird stuff we're hitting. I will bring it up on the list unless someone tells me to stop.
