I just (yesterday) made the move from LAM/MPI to OpenMPI.  The configure / compile / install went smoothly (version 1.1.1).  However, after recompiling my source and executing it usually crashes in MPI_INIT.  Seems to be coming from the same place MOST of the time.  Usually spits out a message something like this.

Signal:10 info.si_errno:0(Unknown error: 0) si_code:1(BUS_ADRALN)
Failing at addr:0xfdff8018
*** End of error message ***
Signal:10 info.si_errno:0(Unknown error: 0) si_code:1(BUS_ADRALN)
Failing at addr:0x2807000
*** End of error message ***

The test system (before moving back to the cluster) is a G4 PowerBook with OS 10.4.8 (not using Xgrid at the moment).  I'm oversubscribing it (2 processes, it knows there is only one).  Attached are the config info from the install.  And listed below seems to be the crash point from the mca_bml_r2_progress function.  Any help is much appreciated.
