A friend of mine who lives and breaths this stuff (I wont tell you what
he does - but suffice to say he's authoritative) basically said to me on
something about serial ports that you can't go wrong with USB stuff,
even on Linux.
Would that work?
Serial ports certainly are getting scarce! You'd get 2 to a board an
embarrassingly long time ago!

However, mobos with a serial port are becoming harder to find.
That's not really been my experience, they just moved it to a header.
You will need to supply a DE9 to ribbon cable, say on a bracket, or
installed in a cutout elsewhere in the case.
This is the first one that I checked, and it has such a port labelled
COMA, along the left/bottom edge.

Also note that the Linux PPS driver supports the standard PC parallel
port, which you can usually find as a header. If you are having
performance issues with one, try the other. (But you may need to supply
negative-going edges to the parallel port.)
Have fun,
Darren
