I just verified it with our OpenPA developer.  We don't have sparc 
processor atomics.  On solaris we use libatomics; if not, it uses the 
lock-based emulated atomics.

This might be a bug in OPA.  Can you send us the log of the OPA 
configure?  Also, a log of the mpich2 configure will be useful.  If you 
are using --with-device=ch3:sock, it doesn't use OPA, so it won't matter.
