If it helps anyone, here's a trace I scribbled manually. I have
vinum_load="YES" in /boot/loader.conf, but booted into single user.
The root fs is plain UFS2. This is what I get when I start vinum:
# vinum start
panic: unmount: dangling vnode
Debugger("panic")
Stopped at Debugger+0x54: xchgl %ebx,in_Debugger.0

(with lots of arguments for each function that I can provide upon request).
