No difference; sequences of 8 spaces in indentation are still highlighted.

Okay.

Two different things:

 * whitespace-check-indent-whitespace--when non-nil--doesn't play
   nicely with indent-tabs-mode; this has been the case for as long as
   I know.
 * Setting whitespace-check-indent-whitespace to nil simply doesn't
   work. That is, it doesn't turn off checking (and correcting)
   indentation whitespace.  This is (relatively) new.

Unfortunately I don't have a working copy around that hasn't been updated 
to a point that includes this problem. I'm not sure when I updated prior 
to my most recent update (April 1); it was a while. I'm in the process of 
checking out some older revisions to try to find when this worked; but so 
far no luck. I can say that it works with emacs 21.4.1.
