I'm currently using the latest version of CentOS which I believe is based on 
RedHat Enterprise Linux 4 Update 4.  I had upgrade to the lastest kernel 
which is 2.6.9-42.0.3.ELsmp.  From what I've seen, 3ware support wasn't 
available directly from CentOS until a few months ago (I'd guess at half a 
year or so).  CentOS 4.3 was apparently the first to offer it, but not 
initially.  As far as I can tell, everything is up to date, unless the 
version the CentOS team is using is out of date.
