These values *could* be correct (not all PnP BIOS:es can be trusted, apparently). What we need to do really, is to get PnP working properly with smsc-ircc2 and the pass these PnP settings through as if they were parameters to the module, in the call to smsc_ircc_preconfigure_subsystems() in the smsc_ircc_init() call. Then it will (probably) preconfigure the bridge for the correct ports all the time.
The static table I've put in there just happens to be factory defaults on a few machines, subject to change whenever some HW is added/removed I believe.
