Afaik pvops (even /next) also has no pci_backend support yet and even 
the pci_frontend support is mainly untested.
Both (front/back) work great with Andrew's 2.6.29 tree, although I 
haven't seen ANY reports of IA64 running off it.
I would also consider pvops to be a moving target (you know... lkml fun) 
so I wouldn't really base anything on it until the structure has been 
approved. Maintaining two different pvops lines (one with all changes as 
requested by mainline maintainers and one "stable") might to much of a 
burden if we already have a working 2.6.29 with (hopefully) not much 
work to do other than extensive testing before announcing it as 2.6.18 
successor.

Best regards,
