1.9.x slices, newfs, and vinum problem?

My apologies for not testing earlier .. I'm trying to get my 'test lab'
up to speed in general, so unfortunately I haven't been following the
bleeding edge for all the features I'm using..
Am working on setting up a (physical) test machine running -HEAD as of
about a week ago. Don't think this is an issue as the relavent files
don't appear to have changed since my build.
I am able to create a simple vinum volume as follows:
drive d1 device /dev/ad1s1a
plex org concat
sd length 6g drive d1
which passes the 'dd' i/o test
(as well as a more complicated striped volume on ad1s1a and ad3s1a)
but 'newfs -v /dev/vinum/vk' fails
without -v : newfs: /dev/vinum/vk: unable to retrieve geometry
with -v : newfs: /dev/vinum/vk: is unavailable
dmesg snippet as follows:
vinum: CONFIGURATION OBLITERATED
ad1s1: type 0xa5, start 63, end = 78156287, size 78156225 : OK
vinum: drive d1 is up
ad3s1: type 0xa5, start 63, end = 78156287, size 78156225 : OK
vinum: drive d2 is up
vinum: vk.p0.s0 is up
vinum: vk.p0.s1 is up
vinum: vk.p0 is up
vinum: vk is up
vinumioctl: invalid ioctl from process 759 (newfs): 40886468
So it looks like the disklabel rework broke some assumptions somehow..
on a quick inspection :
sbin/newfs/newfs.c was changed to use the DIOCGPART ioctl to determine
the partition info, rather than an internal? getdisklabel() call
but DIOCGPART is not implemented for vinum, hitting the 'error' case
in newfs (and explaining the dmesg), which then checks for -v. if no
-v, newfs gives 'unable to recieve..', if -v, nfs uses the stat()
information , assuming the target is a raw file (as newfs was updated
to work with raw files, which is overall useful)
essentially, my guess is that it looks like vinum needs to be
reworked to support the or similar new DIOCGPART ioctl..
So.. I know vinum isn't used by everyone.. if this sounds like the
problem, I can try to take a crack at fixing it, but I doubt I can make
the release branch .. e.g ~1 week at the earliest, owing to my n00b-ness..
