It doesn't make any difference trust me.  I tried genkernel a few months ago 
with the --bootloader=grub option and it it removed everything in my 
grub.conf as well ; the file was 0 bytes afterwards. Lucky for me, I keep 
backups.
  I've never really liked Genkernel though and don't use it. Most of the time 
when I update my kernel it is pretty quick and easy:

I turn on the symlink USEflag which makes a new symlink of my new kernel.
So, after I emerge any new kernel source I just cd /usr/src/linux then 
zcat /proc/config.gz >.config  which copies the config from my current kernel 
then run make oldconfig (any new changes will prompt you); then make 
menuconfig if I want to change anything, otherwise make all install 
install_modules

Then just reboot.  I already have grub configured to use either the vmlinuz 
symlink in /boot which points to my latest kernel image or the fallback  
vmlinuz.old which is my previous kernel image.  The make install copies these 
files into /boot automaticly.
