And keep in mind that our system ran fine once installed. I've sent 
mail to the owner of the system that had problems to see if he has anything
to report on what 3.4 or 3.3 does for him

Duh. What have you hooked up to the 1740? Is it a plain 1740 or a 1740a?
Do you have both internal and external scsi devices connected to it? If so,
DON'T. 1740 is overly sensitive to cabling, something Adaptec fixed on
the 27xx series.
