The newer ACPI tries to begin to describe what is on the other end of serial busses being used for internal purposes. Now there are several good reasons we want to know what is on the end of a port already that are not currently handled, and I have suggested a port "type" attribute would be useful (eg unknown, modem, bluetooth, ax25, dcc, etc) so the kernel can help user space enumerate in user friendly fashion. Where it gets slightly more tricky is that we are beginning to see systems where the firmware is describing serial port (and power management) device behind port (and power management) so there is a power management hierarchy involved. But yes - these patches should have been labelled 'RFC' - the concept needs discussion in public not the current code drafts.
