OK. This is more or less the path I'm following: getting the node-form array
passing it the $node object. This will set the #default_value everywhere.
Then I copy the #default_value values into #value and set #need_validation.
Then I do a drupal_form_validate().

Problem here is: form_set_error() keeps a static variable of the errors on
the form. So if you want to import *two* nodes, the errors of the first run
will still be present in the second run with no way of clearing them.

form api 2.0 will be focused on making things like this easy again.

I'm not critizing form api 1.0. I think it works great in most cases. But
not in mine :-(
Seperating data (with validation / submit) and the actual form seems like
the way forward.
