This is from RHEL5 - it's the driver that comes built-in:

[root at serv1 ~]# modinfo 3w-9xxx
filename:       /lib/modules/2.6.18-8.el5/kernel/drivers/scsi/3w-9xxx.ko
version:        2.26.02.007

vermagic:       2.6.18-8.el5 SMP mod_unload 686 REGPARM 4KSTACKS gcc-4.1

The overall responsiveness of the system under benchmarking when 
running RHEL5 is somewhat better than that when running CentOS 4.5.
