I suspect because 38400 x 2 = 76800, which is a pretty weird serial port
speed.
It may also be that the same hardware issues which prevent 57600 also
simply do not allow any "turbo" operation.

Please remember that the so called "DW4" or Turbo roms and drivers are
experimental and unsupported at this time.  As you noted, they are not
automatically built in the standard boot disks.  It is expected that
if you want to experiment with these things that you will have a
NitrOS9 build system and the experience to create these modules from
what is provided.. if this doesn't sound like something you (and I
don't mean you specifically, Bill :) are able or want to do, please
wait until the Turbo stuff is made mainstream.
