Looking at the sizes, I think you may be on to something there. 
/dev/hda2 is 100MB, the default size for a /boot partition.

My guess is:

hd0,0 or hda1  Windows
hd0,1 or hda2  /boot (shared between FC3 and FC4?)
hd0,2 or hda3  / for FC3
hd0,4 or hda5  logical volume containing / for FC4

Please boot your rescue CD, mount /dev/hda2 and tell us what files are 
there.
