IBM ServeRAID 6i compatability

Has anyone successfully installed 7.3 on a machine with IBM's ServeRAID 
6i adapter?  During installation, I am getting a message "No hard drives 
have been found.  You may need to manually choose device drivers for the 
installation to succeed. ..."

Well, I did choose the ips (ServeRAID) driver from the driver list.  
However, the installer still did not see my logical drive.  Is there any 
way to provide an updated driver during installation or is there some 
trick anyone knows to get the installation program to see my logical drive?

I'm sure you are wondering if I have done the obvious like creating a 
logical drive with my raid array - and yes I have done that.

I have installed 7.3 on several IBM xServers with the 5i raid controller 
without any problems.  I really can't go with RHL 9 due to an 
incompatability with some third party software we use.  Any insight 
would be greatly appreciated.
