I don't grok the problem, (i have root lvm on my main system)
/dev/vg01/lvol1         253871     49152    191612  20% /

since the only known way to boot this is by having an initrd
i just put lvm 0.9 tools in the initrd an rebooted

my linuxrc looks like:
#!/bin/sh -x
mount -t proc /proc /proc
echo "" > /proc/sys/kernel/modprobe
insmod -k /lib/modules/*/kernel/drivers/md/lvm-mod.o
