A question about the games.
 

When I try to play games such as Chromium, or ArmageTron, the games are choppy and have a low FPS rate.

I am running Mandrake 9.2 Download Edition. The computer I'm on meets well more than the requirements to use 9.2

The graphics card is a Radeon 9200 with 128 MB of DDR RAM.

I have the right driver.

After that, I really can't tell you much more about the problem unless you directly ask me. Sorry for taking up your time.

Are you using the driver which installed when you installed Mandrake or the Radeon driver from their website?

The one contained within the distribution is a generic driver, the correct driver will need to be downloaded and installed. Your frame rate shoul then be much better.
