According to this page at ntcompatible.com, Medal Of Honor: Allied Assault is supposed to be functional in WinXP.

EA Games also shows, under the game requirements, that it can be run in WinXP:

I suggest that you ignore the warning about the WinXP logo testing when installing the new video card drivers. How well a driver functions in WinXP has nothing to do with whether or not it has been signed by the Microsoft Windows XP Publisher. I'm currently running the older 28.32 driver set from nVidia with a GeForce2 Ti card. These drivers are definitely <i>not</i> signed, and I have had absolutely no difficulties of any kind.
The key to the installation is that you must NOT use the installation launcher (Setup.exe) to install the drivers. They must be right-clicked, extracted into a new folder, and then updated from the Device Manager, by right-clicking on the listed graphics adapter, and choosing "Update Driver". You should then browse to the folder that contains the extracted drivers, highlight the .inf file, click "Open", and the choose your video card from the list.
It may be necessary to install this patch if you have an AMD processor:

Your graphics card is not incompatible with WinXP.
