No, you're not. I have a mix of LVM1 and LVM2 on my machine, running
quite happily with a 2.6 kernel:

    leto:~# uname -r
    leto:~# pvscan
      PV /dev/hdd5   VG os    lvm1 [4.33 GB / 0    free]
      PV /dev/hda6   VG fc2   lvm2 [100.95 GB / 68.95 GB free]
      Total: 2 [105.27 GB] / in use: 2 [105.27 GB] / in no VG: 0 [0   ]

What aren't compatible with 2.6 are the LVM1 userland tools. If you're
using a 2.6 kernel, you'll need the LVM2 tools. The on disk format is
identical between LVM1 and LVM2, so there is no upgrade path per se.
