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
