Thanks for the tip.  lspci returns this:  

09:04.0 SCSI storage controller: Adaptec AIC-7892A
U160/m (rev 02)

I wonder if I should load the aic7xxx driver instead. 
I got an error trying to load that one, which did not
occur with the aic79xx, but it's possible I tried to
use the wrong edition of the aic7xxx.
