Linux driver needed for SN9C203 CMOS Camera 1.3M

Hi! I am runing CentOS 5.0 on my ASUS Z53J laptop through VMware at
the windows XP platform. Everything works fine except for the CMOS
Camera on my laptop.
I only knew that the model No. is SN9C203 and is manufactured by a
company called Chicony.
Does anyone know how I can install it correctly? I have been searching
for the driver on Google for quite a while, but did not find any thing
useful. I will be very appreciating if anyone can help me out.
Many thanks........
