hmm.. well reading through Configure.help[1] i see something[2] that
might look promising, or at least you could check this for option in the
config for whatever version of redhat you're trying now.  not having
one of these toys myself, i guess i can't be of too much help otherwise :)

[1] <path to linux source>/Documentation/Configure.help.  it's where
    all the information used for documenting all the kernel compile
    options are stored, i.e. those informative messages in make menuconfig
[2] (there's some other stuff after this in the file, but this looks the
    most relevant)

Fusion MPT device support
CONFIG_FUSION
  LSI Logic Fusion(TM) Message Passing Technology (MPT) device support
  provides high performance SCSI host initiator, and LAN [1] interface
  services to a host system.  The Fusion architecture is capable of
  duplexing these protocols on high-speed Fibre Channel
  (up to 2 GHz x 2 ports = 4 GHz) and parallel SCSI (up to Ultra-320)
  physical medium.

          [1] LAN is not supported on parallel SCSI medium.

  These drivers require a Fusion MPT compatible PCI adapter installed
  in the host system.  MPT adapters contain specialized I/O processors
  to handle I/O workload, and more importantly to offload this work
  from the host CPU(s).

  If you have Fusion MPT hardware and want to use it, you can say
  Y or M here to add MPT (base + ScsiHost) drivers.
    <Y> = build lib (fusion.o), and link [static] into the kernel [2]
          proper
    <M> = compiled as [dynamic] modules [3] named: (mptbase.o,
          mptscsih.o)

          [2] In order enable capability to boot the linux kernel
              natively from a Fusion MPT target device, you MUST
               answer Y here! (currently requires CONFIG_BLK_DEV_SD)
          [3] This support is also available as a module ( = code
              which can be inserted in and removed from the running
              kernel whenever you want).  If you want to compile as
              modules, say M here and read
              <file:Documentation/modules.txt>.

  If unsure, say N.

  If you say Y or M here you will get a choice of these
  additional protocol and support module options:         Module Name:
    <M>   Enhanced SCSI error reporting                     (isense.o)
    <M>   Fusion MPT misc device (ioctl) driver             (mptctl.o)
    <M>   Fusion MPT LAN driver                             (mptlan.o)
