You can also rework your history by using mq, as long as it hasn't  
gone out of your machine (and ideally is linear, I don't know how mq  
deals with merged branches but I doubt I want to): qimport everything  
from (and including) the changeset to remove, qpop everything, remove  
the offending changeset from your series, qpush everything, then  
qfinish (if the patches applications worked).
