Sorry about that. This is not megaraid its the mpt driver.
LSI SAS3041E-R PCI-e
mpt0: <LSILogic SAS/SATA Adapter> port 0x2000-0x20ff mem
0xd0210000-0xd0213fff,0xd0200000-0xd020ffff irq 16 at device 0.0 on pci3

While I haven't found a way to actually configure the thing in
FreeBSD, the mpt
driver does make some information available via sysctl:
[sp...@uniweb ~]$ sysctl -a|grep dev.mpt
dev.mpt.0.%desc: LSILogic SAS/SATA Adapter
dev.mpt.0.%driver: mpt
dev.mpt.0.%location: slot=8 function=0
dev.mpt.0.%pnpinfo: vendor=0x1000 device=0x0054 subvendor=0x1028
subdevice=0x1f09 class=0x010000
dev.mpt.0.%parent: pci2
dev.mpt.0.debug: 3
dev.mpt.0.role: 1
dev.mpt.0.vol_member_wce: NC
dev.mpt.0.vol_queue_depth: 128
dev.mpt.0.vol_resync_rate: 0
dev.mpt.0.nonoptimal_volumes: 0
Don't test whether the "nonoptimal_volumes" parameter works, it does -
but if you pull a drive, FreeBSD likes to panic both on the loss of a
disk
and then again when the drive is reconnected and the rebuild completes.
This is apparently some problem in the CAM layer, not the mpt driver, but
it's something to be aware of. Scott Long has noted that this is being
worked on in 8.x.

The Linux megacli program does run. You have to mount the Linux device
filesystem (so it can "see" the control nodes) but it is fully
functional and gives you command-line interactivity to the board. You
can absolutely configure and interact with it from FreeBSD.
The program is annoying as heck as by default it writes a logfile on
EVERY INVOCATION, but it does the job and allows you to configure and
maintain the board, which is kinda important as if it detects an error
(e.g. failed unit) it will start beeping - the board has an audible
alarm on it.
I have one of these boards - its quite nice and VERY fast - if someone
wants it I would be willing to sell it (I've got the battery-backed RAM
option on it too, which makes it MUCH faster; that's a
usually-rather-expensive option)
