There are no command-line options that should affect this.  I wonder
whether it could be that the time spent outputting text to the console
avoids a race condition that underlies the problem you're getting?

The issue with hal was that some recent kernel, udev or hal change means
that the usb serial devices don't disappear from HAL-land after a sync,
meaning that gnome-pilot never gets told a palmos usb-serial device has
connected after the first connection.  If you think this is your
problem, try stopping hald before starting gpilotd.  You can then
restart hald, as gpilotd only checks HAL on startup.
