The SoundBlaster brand is so vague now with regard to the actual chips that it's misleading. The el cheapo CompUSA brand card is iirc a very old and generic chip, it's not the best quality wise but when I bought them months ago they seemed to work with everything I threw at them. In all honesty I don't remember testing them with FreeBSD, but it works out of the box with BeOS R5, so I'd assume FreeBSD comes with the driver.
