Followed up with bchui, who says on further analysis, the lampoly looks fine.  To paraphrase his responses:
"I was...  using 0.5um lines patterned on 0.7um 955 resist (on plain Si wafers).  Actually the etch went beautifully--nice selectivity, good sidewalls, etc,.... I etched 1.2um in 210 sec, i.e. 3428A/min, which is just right for Si!"
