linux-k7: grub boot entry missing after upgrade

[root]

Package: linux-k7
Version: 2.6.12.16
Severity: important


Last week, my system was booting fine with linux-image-2.6.12-9.

After doing an apt-get dist-upgrade to pull in the final bits of Breezy
(stuff like OpenOffice and foreign fonts), the only remaining entry in
grub.conf was for 2.6.10.

I was tracking Breezy pre-release, so I had ended up with the k7 build
of 2.6.12-{6,7,8,9}.  It was a long time since I had 2.6.10-*, which was
no longer installed when I tried to boot my system today, causing grub
to complain about a missing kernel image, rendering my system unbootable!

My grub.conf contains entries for NetBSD and Windows XP.  There were
some customizations made to it, however the begin and end autoconfig
block markers still remain as far as I know.  I can't
easily verify my configuration since reportbug now uses Jove, and I
can't even use Control-Z to suspend the editor and read my config file!
