I would have great difficulty allowing such loads if they cannot be
by design - the manufacturer should give you specific assumptions they use
load distribution.  I have used arching action (or deep beam effects) of the 
masonry to justify such walls on thin elevated slabs - but you still need to 
confirm strength or shoring during construction before the masonry wall has 
developed its strength.
