Personally, I'd sure as hell recommend avoiding the Creative ALSA driver - I tested it yesterday and it caused a kernel panic on my gutsy. It was only because I could use recovery mode to login as root and delete the driver again that my system survived, as gutsy started crashing on boot due to the Creative driver.
Just go with the OSS driver for now...
