The current implementation of lazy rules requires you to explicitly call 
them: they are not actually matched.
Therefore, you need to make sure to call the appropriate rule.

One solution, in your case, is to use an if expression in the body of 
the collect iterator:

lazy rule DoA {
from class : MM!derivedA
...
}

lazy rule DoB {
from class : MM!derivedB
...
}

classes->collect( class |
  if class.oclIsKindOf(mm!derivedA) then
    thisModule.DoA( class  )
  else  -- if class.oclIsKindOf(MM!derivedB) then
    thisModule.DoB( class  )
  endif
)

ATL 2006 supports most of ATL 2004 (i.e., "pre ATL2006" as you call it) 
features, with the notable exception of refining mode, which does not 
work yet.

Note 	however, that you can choose which version of ATL to use for each 
of your ATL programs. Thus, if you have one program requiring refining 
mode, you can use ATL 2004 with it, and ATL 2006 with all other programs.

You can find for more information about ATL 2006 on the wiki:

The latest download available from http://www.eclipse.org/m2m/atl/download/
includes the ATL 2006 compiler.
