mystery options

[Atom Smasher]

FreeBSD 6.1-RELEASE
xorg-server-6.9.0_6
nvidia-driver-1.0.9746

---- config file ----

$ egrep -vi ^# /etc/xdm/Xservers
:0 local /usr/X11R6/bin/Xorg :0 -nolisten tcp -logverbose vt9
:1 local /usr/X11R6/bin/Xorg :1 -nolisten tcp -logverbose vt10

---- /config file ----

when switching between virtual terminals (CTRL-ALT-Fn) i noticed this in 
my Xorg-logs:

(II) NVIDIA(0): Setting mode "1440x900_61"
(**) Option "Device" "/dev/sysmouse"
(**) Option "BaudRate" "1200"
(**) Option "StopBits" "2"
(**) Option "DataBits" "8"
(**) Option "Parity" "None"
(**) Option "Vmin" "1"
(**) Option "Vtime" "0"
(**) Option "FlowControl" "None"
(**) Option "BaudRate" "1200"
(**) Option "StopBits" "2"
(**) Option "DataBits" "8"
(**) Option "Parity" "None"
(**) Option "Vmin" "1"
(**) Option "Vtime" "0"
(**) Option "FlowControl" "None"

several of these options i can't find documentation on, and even though 
they're preceded with "(**)" they're NOT specified in the config file. any 
info on this?

thanks...
