Accessing IBM AIX jfs volumes in MacOS X

Nerdy question... We had one last old and ancient IBM RS/6000 server, now defunct, whose motherboard went kaput recently, and we would like to retrieve as much user data as possible. Having extracted the HDDs, which were SCSI-3, using adapters, cables and whatnot we can connect them either to a MBP or a MP running 10.5.2. However, these HDD's (2) are partitioned and formatted in IBM's own jfs (journalled file system) format. Is there any way to read these disks on MacOS X?
