All you have to do is to boot into single user mode ('boot -s' at the
boot prompt), and create the missing device node:

cd /dev
sh MAKEDEV ad4s1a (and probably others, have a look at /etc/fstab).

Then you have to adjust /etc/fstab accordingly (replace da0 with da4).

Now, your system should start properly...
