I have had nothing but problems trying to get grub to boot a lvm root
fs. I use lilo and have no problems at all. Below is the section of my
lilo.conf.

image = /boot/bzImage
        root = /dev/vg0/lv0
        ramdisk = 8192
        initrd = /boot/initrd-lvm-2.4.20-gaming-r5.gz
        label = shadow
        read-only

I don't know about grub but in lilo I always had to give the ramdisk
size.
