It's on my todo list to actually add bisect support to StGIT (someone
suggested it on the mailing list) but I can't give any estimates about
when this would be done. The idea is that it will only bisect the base
and push the patches on top of the new tree (at a first though, it
doesn't look difficult at all).

Otherwise, use StGIT to manage the patches and the following sequence
for bisecting:

$ git bisect start
$ stg init
$ stg pick <patch@branch>
$ stg pick <patch@branch>
$ ...
$ stg pop -a
$ git bisect good v2.6.x
$ git bisect bad
$ stg push -a
$ ... test ...
$ stg pop -a
$ git bisect good|bad
$ stg push -a
$ ...
