      Hello all,
           I would like to read my FC5 LVM disks, duak booted with
    an old
    (~RHEL3) system. If I try vgscan or pvscan on the RHEL 3 machine
    there
    is nothing  visible.

        Should I (can I ) remove the lvm layer from FC5?
       Or would it be easier to graft lvm2 into RHEL 3?

You might try using the trick I used to workaround #186395 in reverse:
Copy /sbin/lvm.static from your FC5 box to somewhere on the RHEL3 
partition (don't overwrite the /sbin/lvm.static from RHEL3 though). 
Let's say you put it in /root/lvm.static
Then, in RHEL3, try:
/root/lvm.static vgscan
If that seems to work, try:
/root/lvm.static vgchange -ay
Paul.
