I recommended installing no bootloader more as a failsafe. You're
right that the installer will most likely get it right. I did the 
manual configuration of GRUB when I installed FC2 on a system with 
WinXP, because I didn't want to run into the dual boot bug. At the 
time I needed my Windows system. 

I guess if you let the installer update GRUB and it doesn't work, 
the worst that can happen is you'll have to edit /boot/grub.conf 
anyway. It's worth a shot if this isn't a critical system.
