Yes. You need an Intel Option ROM instead of the LSI. You need to talk 
to whomever sold you the system and get the Intel OROM. Also just an 
FYI, the isci driver didn't get a lot of the issues sorted out until 
kernel 3.7. The 3.2 driver is quite old and you may run into issues. 
Obviously you already know you can patch the driver to pick up those 
device IDs, but I don't know what the LSI OROM does with the OEM 
parameters and if will provide it to the isci driver properly.
