This is marked fixed because the bug that was preventing kernels from being marked as ok to clean up *in the future* has been resolved. This doesn't change the fact that kernels which were previously marked as not-auto-installed are still marked that way on the system; there's no way to safely undo that. Users who care about this will still need to remove the old kernels on a one-time basis.
And it's fixed in quantal because there's nothing LTS-specific about the problem, the problem is just more severe in an LTS. Fixed the bug description accordingly.
