Is it normal practice for a Mode S transponder to display the aircraft
tail number to ATC?



No.

It isn't displayed to controllers, but a ModeS transponder does transmit
its
serial number which can be read using tools not available to the
controller.
The serial number does translate to the N number so long as the
transponder
is correctly registered. As of now this technology hasn't been
implemented
to the controller, nor is the serial number recorded in the continuous
data
recording archive.

Doesn't the system process the flightid field? Or isn't that
transmitted?

I'm not sure what "system" or "field" you're referring. The computers at
the centers and tracons have no idea if the transponder is ModeS or not.
They only process the beacon code and display the ACID that's in the flight
plan.

The centers and tracons don't have Mode S radars yet?

Some do, some don't. The problem is not the radar or the computer behind it,
bu the computer driving the displays that the controllers see: they don't
get the mode S data.

The centers never have and never will other than a few terminal radars which
are piped into the centers for low level coverage in some areas. The ModeS
systems themselves are located all over the US, but there's no datalink
capability between the sensor and the automation system. So the only thing
forwarded to the TRACON from the transponder is the 4 digit octal beacon
code and the 3 digit altitude.
