This may or may not work in your situation, but I see no reason why not. I have used multiple drivers for WinXP on Win2K3 without any issues. XP and 2003 are the same OS - workstation and server versions.
For example, I have used touchpad, audio and video drivers on a notebook where it's owner wanted to have 2003 Server instead of XP, and no specific 2003 drivers were available.
Never had any problems.
If memory serves, you may have to run setup program in compatibility mode. Unless you install the driver via device manager by browsing to INF file.
Good luck.
