If you didn't figure that already, the session itself doesn't save the
data. Instead it signals clients with dbus that session is saved and
each client using session module save it's state. The code to save the
state is located in egg/eggsmclient-xsmp.c and it uses
g_file_set_contents to save actual desktop file in .gnome2/session. The
function is 

static void save_state (EggSMClientXSMP *xsmp)
