Eric,

Do you have more information about 'megasr' module, which seems able to
manage 'MegaRAID' on LSI 1068 ?

This module is also named 'megaswr'

Here's modinfo output for this module (binary for RH4, but can also be
found for SLES9)
==========================================================
[root@iotiger2 x86_64]# modinfo megaswr.ko
filename: megaswr.ko
parm: low_mem_g:Set to 1 to simulate low mem condition
parm: dbglvl_g:driver-wide debug flag
license: GPL

depends: scsi_mod
vermagic: 2.6.9-22.ELsmp SMP gcc-3.4
==========================================================

=> the module is provided by LSI (I get it from the web from supermicro)
=> the module is under GPL (but sources aren't shipped, nor the GPL
license )
=> the module is shipped with a 'pci.ids' file, with following content:
==========================================================
0x8086 0x2652 "megaswr" "MegaSWR|INTEL-ICH6R"
0x8086 0x2682 "megaswr" "MegaSWR|INTEL-ESB2"
0x8086 0x27C1 "megaswr" "MegaSWR|INTEL-ICH7R"
0x8086 0x27C3 "megaswr" "MegaSWR|INTEL-ICH7R"
0x1000 0x0030 "megaswr" "MegaSWR|LSILogic-1030"
0x1000 0x0050 "megaswr" "MegaSWR|LSILogic-1064"
0x1000 0x0054 "megaswr" "MegaSWR|LSILogic-1068"
0x1000 0x0055 "megaswr" "MegaSWR|LSILogic-1068"
0x1000 0x0057 "megaswr" "MegaSWR|LSILogic-1064E"
0x1000 0x0059 "megaswr" "MegaSWR|LSILogic-1068E"
==========================================================
(note the chip with id 1000:0055)

Hope that you can give us more details...
