No they won't work since there is no Linux compatibility shim for the 
ioctl's.  Also the MegaMonitor utilities leaks shared memory under 
Linux and dies.  Fixes from LSI are slow to come by.

The updated version of the Linux tools do tend to work better.  Running the
ancient FreeBSD MegaMonitor does bad things to your system.  It may
work once or twice but can start breaking other programs on the system.
