Right now, I'd be happy with being able to configure the 3Ware care 
as a plain old SATA II passthru interface and do software RAID1 with 
mdadm - but no, Export JBOD doesn't seem possible any more with the 
9550 (unless the units have previously been JBODs on earlier cards), 
you've got to use their 'Single Disk' config which exhibits exactly 
the same problems.
