Not needed since FreeBSD 6.2 if I recall right.  Forget if I got it in
6.1.

| The two linux "look-sees" are there.

| So it looks like all the pre-reqs are there, but it still doesn't work.

| mfid0: <MFI Logical Disk> on mfi0
| mfid0: 237464MB (486326272 sectors) RAID volume '' is optimal

The linux version sysctl is?  Also I think you need to make sure 
mfi_linux.ko is loaded before linuxsys.ko mounts so you get the emulation
hooks.  Verify that via:
	head /compat/linux/sys/class/scsi_host/*/proc_name
results in one saying:
	megaraid_sas
or it won't think it is there.

The count is good to see if your file system & linux version sysctl
stuff is in the right state.  Once it detects it, then the ioctl should
work.  6-stable, 7-stable and -current all have the latest stuff to
support all of the ioctl stuff as Linux does for MegaCli.  MegaCli
does various things to try to find the card in Linux that is really
strange IMHO.  For FreeBSD it doesn't have to be that complicated.
They unfortunately, have not released a FreeBSD MegaCli which they
could ...
