I want to replace vista with XP on my xps 1530 laptop, can i do this and still use the biometric scanner?

I just bought my dell XPS 1530 laptop. I want to switch from vista basic to XP because I've always had problems with vista. Does anyone know of a program that will allow me to switch to XP and still use the biometric fingerprint reader that came with the computer? Or would it be wiser to switch to Vista Ultimate?
