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
db> trace
Debugger
panic
vfs_mount_destroy
getdiskbyname
open_drive
init_drive
read_drive
check_drive
vinum_scandisk
vinum_super_ioctl
vinumioctl
spec_ioctl
spec_vnoperate
vn_ioctl
syscall
Xint0x80_syscall
--- syscall (54, FreeBSD ELF32, ioctl)

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