There are several obstacles.

MBR needs to find PBR
PBR needs to find /boot
/boot needs to find /netbsd
/netbsd needs to mount /

Even when you can make grub load /netbsd directly from an LVM partition
you still fail because the kernel doesn't understand LVM until it starts
the rc scripts.

For regular bootstrap you need

- LVM support and autoconfiguration in libsa, this helps PBR and /boot
- LVM autoconfiguration in the kernel
