With FC5, boot off the install CD (or DVD), select custom partitioning 
and you should be good to go.  I have successfully installed FC-5 on LVM 
over software raid on two different system--boot partitions being on 
standard x83 partitions on /dev/hda.

FC-6 is another matter altogether as it appears there are serious 
problems with software raid, or sata_promise, or multipath or something 
as I am having problems installing on both systems.  Software raid 
arrays are not being seen (some are, some aren't) and on one system, my 
SATA disks are being ignored!
