Nope. It is equivalent to trying to boot a system with a hosed
partition table. You have to get out a rescue disk that understands
LVM. I believe you can use the install medium in the rescue mode to
do it, but I have never had to do it. I have only one system using
LVM, and I have not broken it yet. (Knock on wood)

I should probably mention that I am not a big LVM fan. But I have
been running Linux long enough that I have a fairly good idea on how
big I need each partition to be. I also tend to have more partitions
then the "average" user, and a large drive for things that do not
get changed when I update. (Music, movies, CD and DVD images, my
e-book collection, etc.)
