As it does in head. Please remember that you have been testing with
a combination of kernel and vnconfig that is known to be sub-optimal.
vnconfig was fixed (in early November, the same time as the kernel was
changed) to deal with this.
Also note that while the combination you're running is sub-optimal, it
is far better than users using netbsd-6 userland with a netbsd-7
kernel experience.
If you really want vnconfig to list all the devices that you have in
/dev, then I think a simple script like this
VND=$( ls /dev/vnd*d | sort -rn -k 1.7 | sed -e 1q )
F=$( mktemp )
dd if=/dev/zero of="$F" bs=1k count=100
vnconfig "${VND}" "${F}"
vnconfig -u "${VND}"
rm -f "${F}"
should make that happen (using the vnconfig from head, or one from netbsd-6).
(This assumes vnds work on tmpfs, I have never tried, if not, use /var/tmp.)
After that, vnconfig -l should list all of the devices, I think.
Just run that script from rc.local (or somewhere like that, before
you will have used all your vnds).
And probably, you might want to add a little error checking (handle the case
where there are no vnds in /dev, or where mktemp fails, or ...)
