The following ought to work, if you are starting from a 2.4 LVM1 config:
1. mkdir /etc/lvm
2. touch /fastboot # this eliminates the fsck
3. Reboot into kernel-2.4 with init=/bin/sh
4. mount -o remount,rw /
# LVM2 won't overwrite non-symlinks left by LVM1
# remove them. (The list of VGs is available in /initrd/dev/.)
rm -rf /dev/<vg1>/* /dev/<vg2>/* ...
sync
mount -o remount,ro /
5. Boot kernel-2.6
