I actually have a set of scripts that I use for this, which I've been too 
lame to clean up properly and send in. The basic idea is:

 (1) "git branch clean mainline"
 (2) "git checkout clean"
      (now I'm looking at the clean history, which doesn't have anything 
       yet)
 (3) "git refine dirty"
      (this says I'm trying to match the content of the head with the 
       dirty history)
 (4) editor window pops up with the diff between the working tree and 
      dirty
 (5) edit the patch, removing hunks which go later in the series, or which 
      I don't want to do at all and forgot to revert.
 (6) it applies the patch; if there are rejects, it goes back to (4)
 (7) normal thing for committing happens
 (8) if there is any difference between the working tree and dirty, it 
      goes back to (4) for the next in the series

I still need to correct the flow control and make it invoke the editor 
automatically and such, and provide some way out of the middle if you want 
to give up or stop without reaching the end, and I have to detect the done 
condition. But the general method does work, provided you're at least 
somewhat comfortable editing patches (with the safety net that nobody else 
will ever see the patch, so it doesn't matter too much if you screw it 
up).

If somebody else wants to clean this up, I can post my version; dunno when 
I'll get around to making it really right.
