"*manual* orm mapping" , I mean doing the sql manually. 
I think a generalized ORM layer isn't really needed unless youre going
to do lots of throwaway  databases, as you might need for some
user  feedback  handling public  web site , which from  interview movie
posted earlier,  is what django was for ,  some mass media/ interactive advertising
web site .
      Wonder if these ORMs do  database versioning well e.g.
you change your object definitions, and  it generates   ALTER TABLE
statements to match.

The problem I have with ORMs is how you map queries, especially joins,
to object space. RoR does this fairly well, and also (and more importantly)
let's you use SQL for the WHERE clause when required, with a minimum of fuss.
The Python ORMs try very hard to map everything to Python, with various neat
tricks, but it's still harder than writing a little SQL.
