Hi James, this patch enables 16-bit CDBs for aic7xxx and aic79xx. aic7xxx actuallys supports up to 32-bit CDBs, so it might be that aic79xx does that, too. But this would include some more hacking, so this is way easier. Please apply.

Enable 16-bit CDBs for aic7xxx/aix79xx The patch enables support for 16-bit CDBs in aic7xxx and aic79xx. aic7xxx can actually support up to 32-bit CDBs, should they ever see the light of day.
