I observed this for my SuSE system, too. I found, LVM was compiled as
a module, but it was not loaded when system startup initialized lvm :-(
I managed to push loading of LVM into initrd. Thus it gets loaded
very early and even may mount root from LVM. Either start mkinitrd
manually with the informations to load LVM, or declare the LVM module
within some config file to get it into initrd.

For SuSE it's in: /etc/sysconfig/kernel.
