I suspect that Ubuntu 9.10 has defaulted to grub2 possibly prematurely
because it wants to iron out the bugs before it releases its next LTS
version in April.

Using a year-old release of grub2 is courageous at best because even
the grub2 versions "bundled" in the alpha and beta releases of Ubuntu
in September-November were misbehaving regularly.

If you do not want to use grub-mkconfig, you can write your own
config. The grub2 configuration file is not rocket science - and the
Ubuntu, Kubuntu, and Arch wikis and help pages now have good
documentation. Basically:

title --> menuentry{ ... }
sda1=(hd0,0) --> sda1=(hd0,1)
kernel --> linux

The root and initrd invocations are the same in grub.cfg as in
grub.conf/menu.lst (but "root" is has a different effect at the grub2
cli compared to the grub1 cli).
