Fedora used to use a three partition layout by default, which would make root 
either /dev/sda2 or sda3.  However, not they defualt to using LVM.. so it 
would look more something like what you had above or this:		
	kernel /vmlinuz- ro \  	
	root=UUID=fb9366fb-7272-41c2-a247-9558c6d0901f rhgb quiet

Where the UUID is the unique ID of the LV within the volume group.  If you 
lose your LVM config/metadata.. you might need to boot from CD (like Knoppix) 
and run some pvdisplay/vgdisply/lvdisplay commands to get all your info back.
