Nack. These PCI device IDs are reserved for third party device drivers.
Most likely that machine has a third party OROM as well.
OROM = option ROM? Yes, it has the "white" C600 expansion pack, so we
can use all 8 ports of the SAS controller. But we do not want (and
actually cannot) use the Intel-provided megasr driver (the machines run
Debian Wheezy with the 3.2 kernel).
Can we get the controller to use the "regular" PCI ID instead?
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.
