That works like a charm, the new kernel is (re)building world now. 
So far the only surprise is that top quit with a segfault, which 
hasn't happened in a very long time. Buildworld seems undisturbed,
the gstat script is still running. 

Where will the output go?  Serial console?

Thank you very much!
