Argh. After running apt-get install --reinstall grub-pc, lvm is now listed in
/boot/grub/grub.cfg, and grub2 is able to boot the system correctly.
Please don't close the bug, though - this has happened to me several times in
the past, and running grub-install after a couple grub-pc updates resulted in
the same kind of error. I absolutely have no clue as to what just happened
there.
