Check the labels. Probably grub is using the wrong labels to mount the 
root filesystem (and other filesystems you may have). One way to test is 
editing the grub entry at boot time (press any key when the grub menu 
appears, choose the FC6 entry and press "a" to edit the kernel 
parameters) and replacing root=LABEL=/ by root=/dev/hdaX , so it 
explicitly points to the device where the FC6 filesystem resides. This 
way , there's no chance the FC4 partition will be mounted by mistake.
