Managed to sort out the problem by booting both the installer and the installed kernel 2.6.27-X with the parameter iommu=soft. iommu=off did not work. Attached you'll find a lspci. Hope it helps. I've seen the guys at Red Hat updated their kernel in Red Hat Enterprise 9 with a workaround for this issue, which is related to MSI (IBM's Calgary implementation) and not the disk controller by LSI.
