Well:

./dev/mpt/mpilib/mpi_cnfg.h:#define MPI_MANUFACTPAGE_DEVID_SAS1068E             
(0x0058)
./dev/mpt/mpilib/mpi_ioc.h: *  03-11-05  01.05.08  Added family code for 1068E 
family.
./dev/mpt/mpilib/mpi_ioc.h:#define MPI_FW_HEADER_PID_FAMILY_106xE_SAS      
(0x0004) /* 1068E, 1066E, and 1064E */

And mpt(4) has "LSI Logic AS1064, LSI Logic AS1068 (SAS/SATA)" listed as 
supported.

So as far as I can tell it should be supported, assuming it truly works in 
practice.

Given past history in trying to find suitable controllers I have to be 
paranoid and wonder what I am missing... surely I cannot have found the 
perfect controller.

Does anyone have hands-on experience?

I especially like the SAS support; particularly since I have recently noticed 
the availability of low-cost 7k2rpm SAS drives.
