Well, I think the factor there is that we "usually" want users to upgrade to
the latest kernel automatically, whereas users of petsc usually can't
auto-upgrade to the new API.

No, I certainly think that packages like linux-image-2.6-686 should be kept
around.  And you've also made a case for why it may be useful to keep
petsc-dev around.  In any case, it's ultimately the ftp team's decision to
make; it sounds to me like all the arguments have been made at this point.
