[CentOS] CentOS 5.5 does not recognise SAS drives with LSI 1068E Controller

I need to do a new CentOS net install on a new server having the
Supermicro X7DVL-3 motherboard:
Based on that info I assume the board having a "8x SAS Ports via LSI
1068E Controller". We received the server with 3 drives + 1 spare as
hw RAID-5 preinstalled. During bootup I see that the drives are
initialised and everything seems ok.
The issue I am facing is that when trying to install CentOS no hard
drives are recognised.
I am a bit confused as others have reported CentOS 5.3 and 5.4 working
"out of the box" with the same controller:
So I assumed that the megaraid_sas driver shipped with CentOS should
support the controller?
What confuses me also is the output of lspci:
MegaRAID SAS 3208 ELP
Does this mean its not the 1068E controller inside but something else?
Or CentOS misidentifies it?
So I assume the controller is not supported and I need a binary driver
for it. For 1068e it should be:
and the driver I need is inside the file
But how do I go applying this driver during installation as the server
has no floppy drive?
And what happens if I get the driver installed and then the server's
kernel is updated? Do I need reinstall the driver somehow?
