Did you install grub in the MBR for both releases, or have at least one 
with grub installed in the root/boot partition instead?

In the latter case, you can configure one grub to chain-load the other.

In the former case, you'll either need to manually copy grub.conf 
entries from FC4 into your FC5 grub.conf (and repeat this every time you 
get a new FC4 kernel), or you could install grub in the FC4 release's 
root/boot partition and have FC5 grub chain-load it, which would be a 
better solution.
