Did the drives work from the operating system *before* the add_drv command was
executed?  I wonder if, as the add_drv man page says...

     It is possible to add a driver for a  device  already  being
     managed  by a different driver, where the driver being added
     appears in the device's compatible list before  the  current
     driver.   In  such cases, a reconfiguration boot is required...
