Intel SASMF8I

Hello,
this card (using LSISAS1068(E)) is not recognized by FUSION_SAS, after patching the device code it appears to work nicely.

I was 99% of the way there to submit a similar patch (actually there's a few more places where you want to add the new ID), but noticed a previous discussion when a comparable patch was rejected. Turns out there was a jumper on my motherboard (Supermicro X8DT3) which switches between "raid" and "regular" mode (except they were called something much fancier), and the regular mode switches the PCI ID to 0x58 which in turn is recognized. [And the mptsas driver doesn't support the RAID features anyways... there's a what appears to be proprietary driver for that, megasr, which I did not need.]

SASMF8I doesn't seem to have any jumpers for "regular" mode and I don't want to use the sw raid of the chip. As far as I remember megasr didn't let me access drives directly. Is there no option then, except patching locally?

I think we should add it in that case. There's no reason to cripple Linux on hardware just because the bios pretends it has some useless fake raid capabilities.
