Yes, Vista drivers will work well for you if need be.
I don't find your model on the provided link from Kemical. It is probably too old.
I can find or make a driver for you if needed. Hopefully you installed 32 bit version of Windows 7. That would make life easier for you to deal with this.
If you want me to look or make something, please tell me which version you have installed. Then -
Open device manager. Right click on the wireless network card that needs the driver. Properties. Details tab. Change the dropdown to say hardware ids. Then copy/paste the results below that to here.
Edit - Seems I haven't read that legacy part so well before, from Kemical's post lol.
If you have 32 bit, install this that I found by following his...
