I did get one machine to "unclean" cluster state using elrepo's kernel 3.7, but that kernel doesn't boot on most of our boxen (boot-time oops in pata-acpi). It looks to me that unless inktank backports rbd.ko to 2.6.32, centos/sl users won't be able to test ceph for a couple of years: until centos 7.1 comes out and we get the chance to reimage our hardware.
