That looks like the right patchset, I would not expect
that it is -too- difficult to backport to 1.3.1, although
I have not looked...  Your other workaround is to use
an older mkfs that does not make AGs > 4G (or explicitly
specify 4G AGs with your mkfs).

Probably the latter, although I'm not quite certain yet.
