In PET (at least in Bernd's version) it is possible to configure whether dependencies should be checked before or after processing of lexical rules. There is a concrete issue for German: in my current version of the grammar I derive the nonseparated lexical entry from the separated one by means of a morphological rule. Main branch LKB appears to check for  chart dependencies after application of spelling rules, which gives the desired results. As Bernd assures me, this is also the behavior in PET (though I will check this later today). Application before any rules, however, will be pretty useless for German.
