In usual situations, the NetBSD bootloader is able to load kernel
modules for the kernel when starting it. As Michael said, this is not a
usual situation here.

However, it might be possible to create a NetBSD ramdisk, have it stored
inside the kernel (so that it works with Grub) and place the basic LVM
tools required on it. My
current-work-on-cgdroot-which-I-must-commit-this-week is doing a similar
thing - and likewise, I do have to hardcode the ramdisk into my Xen
kernel when virtualizing.

HTH,
