Lucid installer does not detect Valencia/Interlagos/Piledriver systems

[Frediano Ziglio]

From a machine which such family of processors we have

vendor_id : AuthenticAMD
cpu family : 21
model : 1
model name : AMD Opteron(TM) Processor 6212

however in kernel/i386.sh (base-installer sources) you have

        case "$VENDOR" in
            " AuthenticAMD"*)
                case "$FAMILY" in
                    " 15"|" 16"|" 17") # k8
                        echo 686$BIGMEM
                        ;;
                    " 6") # k7
                        case "$MODEL" in
                            " 0"|" 1"|" 2"|" 3"|" 4"|" 5")
                                # May not have SSE support
                                echo 586 ;;
                            *) echo 686$BIGMEM ;;
                        esac
                        ;;
                    " 5") # k6
                        echo 586
                        ;;
                    *) echo 486 ;;
                esac
                ;;

so the system is detected as 486 and an old kernel is installed. In our case (XenServer user) this cause the installation to fail.

I think it would be better to check if FAMILY is greater than 15 then is 686$BIGMEM.
