MPLS, disjointed OSPF area 0 and sham link

Guys, what about this scenario (I posted as reply on older mail, but
no answer, so here it is again):

Lo0 Lo0
 | |
PE---------eigrp---------PE
 | |
 | |
Ar1 Ar2
 | |
CE1 CE2
 | |
Ar0 Ar2
 | |
 | |
RT1---------Ar2----- ----RT2
| |
 \--------backdoor---------

CE1 - PE running OSPF in vrf VPN-A
CE2 - PE running OSPF in vrf VPN-A

Loopback interfaces of PE routers are in EIGRP domain and MPLS is
using them as transport addresses (mpls ID).

Provider has EIGRP in his core network. Not one PE router has
connection to Area 0. How to solve that problem so that VPN sites can
exchange OSPF routes. After that, it is neccesary to make sure that
customer traffic goes through the MPLS clooud, not backdoor link.
My problem is how to solve problem with non-area0 connecting to PE
routers and how tu use sham-link after that. No static routes allowed
:)
