because sometimes there is a lot of overhead that comes with cck that  
you don't really need.

and you spend more time working against what cck gives you by default  
than you do just writing it yourself

and the dependencies for your module explode making upgrades a lot  
messier

Anyway, to answer the question, i know in d4.7/d5 you could do  
form_set_value('field][field', 'value') to set fields
in the validate functions, i don't know if in D6 you can just modify  
the $form_state.
