Yes, there was a fork. The kernel aic79xx got various fixes and got
integerated better with the scsi subsytem, using generic, fully debugged
code instead of it's own, etc.. Unfortunately there's also various fixes
in the adaptec releases which need to be brought back. They are sometimes
non-trivial and until a short time ago non of the core SCSI developers
had aic79xx hardware. The fixes will be merged back one day, similar
to the aic7xxx where this happened.
