pv_ops dom0 is still under development, and right now (as of yesterday)
starting to work.. for me :) 

If you need stable dom0 kernel right now you need to go for 2.6.18 based tree.. 

Or then just use for example RHEL5 or CentOS5, they contain stable Xen
packages/kernels based on 2.6.18 tree with latest drivers and bugfixes added.
