I'm afraid I don't see how that:

internet --> Firewall --> Lan

internet --> Firewall --> DMZ

would be any more secure than this:

internet --> Outer Firewall --> DMZ --> Inner Firewall --> LAN

or this:

internet -->  Firewall --> LAN
                            --> DMZ

which are the setups that I've seen.  Can you give some 
justification/explanation on why you think that would be better?
