Kernel 3.4.6-2 is installed but it does not appear as boot option although there is an entry in /boot/grub2/grub.cfg:

menuentry 'Fedora (3.4.6-2.fc17.x86_64)' --class fedora --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-047568b1-c806-4a34-a4bc-f188264dc3e8' {
        load_video
        set gfxpayload=keep
        insmod gzio
        insmod part_msdos
        insmod part_msdos
        insmod diskfilter
        insmod mdraid1x
        insmod ext2
        set root='mduuid/e74b42397715f5b5a0cb22deefeb3a5e'
        if [ x$feature_platform_search_hint = xy ]; then
          search --no-floppy --fs-uuid --set=root --hint='mduuid/e74b42397715f5b5a0cb22deefeb3a5e'  09f33b13-b722-4321-84a7-f2167220d718
        else
          search --no-floppy --fs-uuid --set=root 09f33b13-b722-4321-84a7-f2167220d718
        fi
        echo 'Loading Fedora (3.4.6-2.fc17.x86_64)'
        linux   /vmlinuz-3.4.6-2.fc17.x86_64 root=/dev/mapper/luks-906ec399-c797-4d9c-8cb0-91e66dd62ad5 ro rd.lvm=0 rd.dm=0 SYSFONT=True  KEYTABLE=br-abnt2 rd.luks.uuid=luks-8f7ede84-309c-4504-9792-e049ef55f705 rd.md.uuid=43544800:8b65b2d9:65fc4d69:4095800b rd.luks.uuid=luks-906ec399-c797-4d9c-8cb0-91e66dd62ad5 rd.md.uuid=e74b4239:7715f5b5:a0cb22de:efeb3a5e rd.md.uuid=85b41a35:96a82ab8:2db5deae:533b944b LANG=en_US.UTF-8 rhgb quiet nouveau.modeset=0 rd.driver.blacklist=nouveau
        echo 'Loading initial ramdisk ...'
        initrd /initramfs-3.4.6-2.fc17.x86_64.img
}

How to make the boot option appear?

F17 comes along with grub2.

Please login to a bash with root and make this command:

grub2-mkconfig -o /boot/grub2/grub.cfg

After a reboot the entry may appear.

This looks like a grub 1 boot entry.

For the new format, you might want to use something like:

title Fedora (3.4.6-2.fc17.x86_64)
    root (hd0,1)
    kernel vmlinuz-3.4.6-2.fc17.x86_64 root=/dev/mapper/luks-906ec399-c797-4d9c-8cb0-91e66dd62ad5 ro rd.lvm=0 rd.dm=0 SYSFONT=True  KEYTABLE=br-abnt2 rd.luks.uuid=luks-8f7ede84-309c-4504-9792-e049ef55f705 rd.md.uuid=43544800:8b65b2d9:65fc4d69:4095800b rd.luks.uuid=luks-906ec399-c797-4d9c-8cb0-91e66dd62ad5 rd.md.uuid=e74b4239:7715f5b5:a0cb22de:efeb3a5e rd.md.uuid=85b41a35:96a82ab8:2db5deae:533b944b LANG=en_US.UTF-8 rhgb quiet nouveau.modeset=0 rd.driver.blacklist=nouveau
    initrd /initramfs-3.4.6-2.fc17.x86_64.img
