I think you will be alright: the kernel packages have a dependency of the package grubby, but I don't think that will try to interfere with your bootloader. You might find you need to edit /boot/grub/menu.lst directly after the update.
What might well happen to you if you have the legacy grub package installed is that an update will replace it with grub2. Just something to watch for.
Anyway, thanks for the post: it always helps to have these things sorted into one place I find.
