How to enabled LSI SAS driver in kernel?

[Goi]

Hi,

I'm trying to build a kernel for a blade server, but I can't seem to get the LSI SAS driver in there.

I have tried booting up to Mandriva in the server, and its kernel detects the hardware. When I type an lsmod, I get the following output:

I'm guessing the relevant modules are scsi_transport_sas and scsi_mod.

In my kernel config, I've already enabled the following:
CONFIG_SCSI_MOD
CONFIG_RAID_ATTRS
CONFIG_SCSI
CONFIG_SCSI_DMS
CONFIG_SCSI_NETLINK
CONFIG_SCSI_PROC_FS
CONFIG_BLK_DEV_SD
CONFIG_BLK_DEV_SG
CONFIG_SCSI_CONSTANTS
CONFIG_SCSI_SPI_ATTRS
CONFIG_SCSI_FC_ATTRS
CONFIG_SCSI_ISCSI_ATTRS
CONFIG_SCSI_SAS_ATTRS
CONFIG_SCSI_SAS_LIBSAS
CONFIG_SCSI_LOWLEVEL
CONFIG_MEGARAID_NEWGEN
CONFIG_MEGARAID_MM
CONFIG_MEGARAID_MAILBOX
CONFIG_MEGARAID_LEGACY
CONFIG_MEGARAID_SAS
CONFIG_SCSI_MPT2SAS
CONFIG_SCSI_MPT2SAS_LOGGING
CONFIG_SCSI_DH
CONFIG_SCSI_DH_RDAC
CONFIG_SCSI_DH_HP_SW
CONFIG_SCSI_DH_EMC
CONFIG_ATA
CONFIG_ATA_VERBOSE_ERROR
CONFIG_ATA_ACPI
CONFIG_SATA_PMP

I've also enabled all SATA drivers, as well as most RAID drivers.

What am I missing out here?

I tried to extract the .config from the Mandriva kernel but was unable to do so.

Thanks!
