Amir,
I am discusing the very same issue in my upcoming RAC book. Basically to understand the master of the block, you need to convert the block/buffer name to a to the resource name (combination of X$LE, DLM_RES , GC_ELEMENT and X$KJBR).
BTW Dynamic Remastering not enabled by default in 9iR2 and it is not totally functional. For that matter, even in 10gR1 it is not a true dynamic remastering as it masters the files to the instance and not the objects. Only 10gR2 has the object level dynamic remastering and for testing purpose you can manually remaster the objects using the oradebug lkdebug commands.

Folks, Is there a way to find out what instance has mastered a certain block in 9i2 RAC?
Thanks Amir
