CentOS - Jul 2005 - NetRaid 1Si on Centos4

Hi, I tried to install Centos4 on server with scsi NetRaid 1si. This card 
isnt't support from kernel version 2.6 (old megaraid driver, like LSI 
controller).
What are steps to doing new install with this scsi card? And it will be stable?
Thanks,
         Francesco
