I've done this with IGRP, but never with RIP, you may want to give it a shot.
There is no way (other than statics) that I kow of to get your /25 OSPF routes to be advertised into RIP as /26 without botching up the rest of your network. If you do a summary-address or area range command, that puts a more specific route on R2, thus black-holing the network. If the routes don't show up on R2, then redistribution won't happen.
Hy solution for this in the past has been to use the ip default-network command on R1, pointing to the link between R1 and R2. If this works the same as it does with IGRP, then you won't get the routes into R1's table, but you will have full connectivity.
