In grepping the source packages, none of the affected packages actually use the broken bits of the ABI (dbi_error_flag).
That said, its still important to provide a consistent ABI for upgrades in case somebody has written something that does use libdbi.
I've tested building rrdtool and libdbi-drivers with the proposed 0.8.4-0ubuntu1 from the merge proposal, so far no problems and rrdtool works fine w/ its DBI mode, libdbi-drivers passes all of its internal test suite.
