Okay.  Well, the simple try didn't magically work.  I added a few lines in
dev/mpr/mpr_pci.c in releng/12.0, built a new ISO, and booted.  Now it
recognizes the part, but says the following:

pcib7: <ACPI PCI-PCI bridge> [...]
pci7: <ACPI PCI bus> numa-domain 0 on pcib7
mpr0: <Avago Technologies (LSI) SAS3516_2> port 0x7000-0x70ff mem 0xb8000000-0xb80fffff,0xb7f00000-0xb7ffffff,0xb7e00000-0xb7efffff at device 0.0 numa-domain 0 on pci7
mpr0: IOC in fault state 0x0, resetting
mpr0: IOC in fault state 0x0, resetting
mpr0: IOC in fault state 0x0, resetting
mpr0: IOC in fault state 0x0, resetting
mpr0: IOC in fault state 0x0, resetting
mpr0: IOC in fault state 0x0, resetting

There is about a 4 second pause between each of the "in fault state, resetting"
lines.
 
This may not be a freebsd-stable converstion any longer.  I'm going to
switch over to freebsd-drivers, unless someone has a suggestion of a
better list for trying to figure out if small adjustments can be made to
the mpr driver to accept this device.

Thanks all.
