8.0-B4 gstripe / GEOM_PART_* upgrade woes

[Stephen Hurd]

I've upgraded from 7.2-RELEASE_p2 to 8.0-BETA4 and using GEOM_PART_* 
with my sliced gstripe array causes the /dev/stripe/raid0a to disappear 
and the reset of the /dev/stripe/raid0[a-z] file systems to be unmountable.

My gvinum array is still working fine and, after chasing the ad* slices, 
they can be mounted as well.  It's just the gstripe slices which are 
corrupt/missing.

When I build without GEOM_PART_* and use GEOM_BSD and GEOM_MBR, it works 
fine.

I've attached an archive with various command outputs which may be 
helpfull... the 8.0 directory is 8.0 with GEOM_PART_* and 8.0-OLD is 
using GEOM_BSD and GEOM_MBR.  I'll paste the 8.0 ones in here in case 
attachments are stripped:
