You really do want to get the newer drivers in place as there is an
issue running
smartctl through that driver to SATA devices.  The new driver fixes the problem.
modinfo /path_to/mptsas.ko

modinfo mptsas.ko
filename:       mptsas.ko
version:        4.26.00.00

Note that the in-kernel drivers may not be up to the latest from the vendor.
