"install" FC6 over top of an FC5 system using LVM?

The short answer is yes.  However, see 
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=208947
for one instance of a problem.

I have a test system which is LV over software raid 5 and have been 
testing multiple linux distributions on it for over a year now.  The 
current Debian, SuSE, Mandriva and FC distros will see the LVs at 
install time as long as you select manual or expert partitioning.  All 
will also allow you to create the LV from your existing 
drives/paritions.  I reuse the LVs, rename the LVs, reformat them, mount 
them without formatting (I have /home on an LV and use it for all FC 
test installs), etc, and never have had a problem until FC6T3 and 
beyond.  There is a strong possibility that 208947 is a hardware 
problem, but no diagnostic shows it and I can get a completely normal 
FC6 or current Rawhide installation as long as FC5 or a non-FC/RHEL 
distro was booted last.
