Yeah -- bummer that !
I assume it'll be sorted out by the kernel HACKers, but til then, you may care 
for a HACK I have for devfs.  If you add to /dev/devfsd.conf (or whatever)
	LOOKUP  ^lvm.$    EXECUTE /choose/your/path/makedev $devname $mntpnt
and then have in /choose/your/path/makedev a script which does a mknod e.g.

#! /bin/sh
# $Header: $
#
# Script to be called by devfsd via /etc/devfsd.conf and /etc/devfsd.cl
# to ensure /dev/mouse, /dev/lvma, etc. exists if it is missing ...

# (echo $0: $1 and $2) >> /tmp/m-l
case "$1" in
