I think if you think about the boot procedure you will determine what you
are doing wrong.  Ask your self the question, how will you boot from sector
in a partition after booting from the MBR?  Ans. It won't happen.  So what
is the problem.  You are booting from the MBR period and is getting the
grub.conf for FC2 and what is in that file cause that is what can be booted.
Now if I remember my GRUB manual chain loading is done for foreign OS's and
FC3 is not a foreign OS.  In the install of FC3 I don't see that you had to
do anything.  GRUB should have found all os's and updated the right
grub.conf with the correct entries.  Now I might be incorrect but this is my
opinion.
