For the archives, I ended up solving it like the following:

Booted with rescue mode on fedora DVD. Do not select to find local

lvm vgscan -mknodes

lvm vgchange -ay

mkswap -c /dev/VolGroup00/LogVol01

fsck -a /dev/VolGroup00/LogVol00 # took a long time

Had to redo the swap, because Fedora boot hung at the enabling swap step.

I don't know how the corruption all happened in the first place.
