    I can't be 100% sure (because once you are using LVM you really don't need
    lots of partitions - so I only have a few ( some combination of root, boot,
    swap and lvm) on the most populated disks, but I believe the answer is yes.

    You can easily try it on your spare partition. Just use

    pvcreate /dev/hda12

    followed by

    vgcreate vg /dev/hda12

    followed by

    lvcreate -L 200M -n test vg

    (or whatever size you want)

    mkreiserfs /dev/vg/test

    and then try and mount it and use it.

    When you are done unmount it and then

    lvremove /dev/vg/test

    vgremove vg

    pvremove /dev/hda12
