A search for "GeForce4 440 Go" on Nvidia's website brought up only unix drivers, but some press releases too about different kind of machines which were equipped with this card.
For example, Windows XP drivers for Toshiba Satellite (5005-S507, 5005-S508, 5005-S504, 5105-S701, 5105-S608, 5105-S607, 5105-S502, 5105-S702, 5105-S901, 5105-S501)http://cdgenp01.csd.toshiba.com/content/support/downloads/s511vidx.exe
for a Dell machinehttp://www.dell.com/support/drivers/us/en/19/DriverDetails/DriverFileFormats?DriverId=7TG9R&FileId=2731105334
