Using 'git bisect' on the GHC tree

Hi all, I am trying to track down a build failure on PowerPC that was introduced some time this year. Usually, the easiest way to do this is by using 'git bisect'. Unfortunately, this doesn't work with the GHC tree since its easy to go to a GHC revision which is incompatible with one of the many GHC sub-modules (eg Cabal). Given a GHC git commit hash, is there a way to get the various libraries into a state where I can build the GHC version specified by the hash?
