Am I correct in understanding that this is about the same amount
of work as is needed to reach the serial port super IO chips?

The BAR is just an address at which the controller will listen -
right - or does it have to be backed by system RAM?

Indeed PCI accesses must be seen by the controller for it to matter
in the first place.
