I'm not sure how you created your entries for FC4T1 without installing 
grub somewhere and copying the correct entry from the FC4T1 
/etc/grub.conf file.

I normally install grub to the boot record of the partition that I'm 
installing the new system to and then copy the entry from the new 
system's grub.conf file into my master grub.conf file for the system I 
have controlling the MBR.  Others will tell you different ways to do 
this, like using chain loading to secondary grub installs.

The partition label can be replaced with an actual reference to the 
device.  Below is part of my grub.conf.  Note that the first three 
systems refer to the boot partition with a label, but the next two refer 
to the boot partion as /dev/hdxx.  Both will work.  You need to know the 
particular label for the partition to use the label, whereas you only 
need to know the device name for the other technique.
