If you're planning to use fakeraid under Linux the general consensus is 
to use Linux software raid ("md") instead.  There is your compatibility 
right there -- the disks can be transported to any Linux system.  Linux 
software RAID will perform better and provide more control from the 
running system.  It is my theory this is why the fakeraid 
implementations do not make it a priority to provide Linux drivers -- it 
is primarily geared towards Windows users.
