Having said that, I still support the original version
of the aic94xx and the SAS stack, which now includes
SAT-1 conformant SATL.

It has allowed some people to upgrade their kernels to
the latest kernel version (as in from git repo), and reported that
it is more stable (i.e. working as opposed to not, including
supporting SATA devices in SAS domains) than the in-kernel version.

It also keeps the sequencer fw together with the driver source
code, so the end-user wouldn't have to mix and match fw version
with driver (kernel) version.
