it's still necessary when GRUB is the the bootloader and is unable to 
read the root filesystem.  btrfs is an example.  GRUB 0.9x can't read 
it and is not being further developed.  GRUB 2 can't read it (yet ?)

With GRUB 0.9x it is also a lot simpler to have a separate boot 
partition when the root filesystem is on LVM.

I also like the grub partition of a few MiB.  Something I can fall 
back to if some misbehaving distro takes control of the boot process, 
but does not identify all bootable systems.

The bootloader on this little partition can be completely self-
contained with Grub 0.9x and can be maintained from a rescue CD - not 
so with GRUB 2, which must execute configuration procedures from a 
running OS, on a different partition.
