The built in
nv driver for Xorg supports the card just fine for 2d funcions.
nVidia has linux drivers, and
SlackBulds has a slackbuild for the driver.
Nvidia has a legacy driver for really old cards, which your fx5200 does not fall into. I use the newest driver with my fx5500. On Nvidia website they detail which cards are supported by which driver.
If you have issues with the newest driver, you can always downgrade to the legacy one.
