[CentOS] Sound Blaster Live! 24bit how to get it support?

Hi,
I used to use the onboard sound card(SIS) and it work well with centos 
4 stock and unsupported kernel. I have just got a new Sound Blaster 
Live! 24bit and installed it on the system. The current kernel does not 
detect the sound card. Is there anyway i can make this card run on 
centos? This is a fairly new card, why the stock kernel does not have 
the driver module compiled from it?
