So, I'd appreciate any help with the two issues that I've summarised
below:
1) I don't seem to be able to get ntpd to receive NMEA data from any
NMEA
source I have available on Win XP, despite having success on Linux (this
also validates my config entries as correct).

Cheers,
Darren
Darren,
I can't help with the second query, and only make suggestions for the
first query. I have run serial NMEA devices on XP, with various versions
on NTP. I've tested both real serial ports, and one Sitecom
serial-over-USB connection. As far as I know all have behaved correctly,
but I have been using the PPS and not just the serial NMEA data, and this
is obviously different to your tests.
I would suggest looking with a different program from NTP to see how well
the serial data is received. Does it work? Perhaps try Visual GPS:

You should also be aware that without PPS, using just serial NMEA data is
likely to provide not better a performance than just syncing to Internet
sources.
The default baud rate for GPS devices is 4800, but I presume you have
allowed for that in your config, as you have success on Linux.
So just some ideas which may help.
Cheers,
David
