A very good point - possibly the major device number is wrong?  Looking
at a 1.3.2 release copy of MAKEDEV I see

        dhu*)   name=dhu; major=34; count=16;
                unit=${i#dhu}   
                case $unit in   
                0) ch=S ;; 1) ch=T ;; 2) ch=U ;; 3) ch=V ;;
                4) ch=W ;; 5) ch=X ;; 6) ch=Y ;; 7) ch=Z ;;
                *) echo bad unit for $name in: $i ;;
                esac;;

but don't recall at the moment what to peruse to see whether the major
matches the DHU index in the device table or whatever it may be these days.
I expect it does and the kernel has evolved some way that has wedged the
driver... sigh.
