Sind sie - das eine ist die hexadezimale Interpretation, das andere die 
dezimale. Siehe unter

https://ssl.nettworks.org/repo/browse/eisfair/trunk/install/eisfair-1/eis-installer/rootfs/var/install/initrd/initrdfs_empty/initparttwo?r=40457

folgende Auswertung in der initramfs, die ja auf den Problem-Maschinen 
nicht durchlaufen wird:

# Check if ROOTDEV is a number (major and minor)
if ! $($GREP -q '^/dev/.*' /rootdev)
then
     string="$(cat /rootdev)"
     echo "rootdev is a number: $string"
     stringlenght="$(echo ${#string})"

     # hdd3 is 1643 (0x1643)
     # sda1 is 801  (0x0801)
     # https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=193730
     case $stringlenght in
       3)
         # Get the major number (first digit only)
         # sda1 is MAJOR 8
         MAJOR="$($AWK '{ print substr($0,1,1) }' /rootdev)"

         # Get the minor number (everything after the first digit)
         # sda1 is MINOR 01
         MINOR="$($AWK '{ print substr($0,2) }' /rootdev)"
         ;;
       4)
         # Get the major number (first two digits only)
         # hdd3 is MAJOR 16
         MAJOR="$($AWK '{ print substr($0,1,2) }' /rootdev)"

         # Get the minor number (everything after the second digit)
         # hdd3 is MINOR 43
         MINOR="$($AWK '{ print substr($0,3) }' /rootdev)"
         ;;
     esac

     echo "MAJOR in hex is $MAJOR."
     echo "MINOR in hex is $MINOR."

     # Convert hex to dec
     # sda1 is MAJOR 8  and MINOR 1
     # hdd3 is MAJOR 22 and MINOR 67
     MAJOR="$(echo $((0x${MAJOR})))"
     MINOR="$(echo $((0x${MINOR})))"

     echo "MAJOR in dec is $MAJOR."
     echo "MINOR in dec is $MINOR."

     # Get the /dev node name using the major and minor numbers by
     # looking it up in /proc/diskstats
     DISKS="/proc/diskstats"
     BOOT="$($AWK '$1=='$MAJOR' && $2=='$MINOR' { print $3 }' $DISKS)"
     $RDEV "/dev/$BOOT"
fi

if [ "`$CAT /rootdev`" = "/dev/" ]
then
     echo ""
     echo "Cannot find MAJOR $MAJOR MINOR $MINOR in $DISKS!"
     echo "This means there is no driver for your hardware"
     echo "in the initramfs or the driver was not loaded."
     shell
else
     echo "rootdev is $($CAT /rootdev)."
fi

Und damit alle wissen, wovon Ihr hier redet, lade ich den Installer mal 
hoch.
