Well ... it is possible :)

Use this hook in t3lib_tcemain for process_datamap:

          $hookObj->processDatamap_preProcessFieldArray($incomingFieldArray, $table, $id, $this);


If you define your hook-method (processDatamap_preProcessFieldArray) like following:

function processDatamap_preProcessFieldArray($incoming, $table, &$id, $parentObj)	{

you will be able to set $id to 0 (because & is used it is a variable passed by reference)

when $id get's set to 0 this record won't get processed further (the initial processing before this
hook isn't doing something tragical until the above hook get's executed) ...

If you agree I will set the bug to "resolved"
