I haven't had to modify anything in the grub config.  There should be an update-grub command (there 
is on Debian) that should build what you need in /boot/grub.  Try putting the defaults back and run 
that command.

I never used grub much because it didn't support /boot on LVM.  grub2 is much better than LILO.  Its 
behavior isn't that hard to grok, although if you have to debug how the boot code is built that's 
more complicated than previous booters.  But I haven't had any trouble with that part.

I have an old box that wouldn't boot with grub2 due to a BIOS problem.  Eventually the Debian 
maintainer figured out how to work around it in response to my bug report.
