Before root is mounted for real, it is actually mounted.  /sbin/init
attempts to remount / properly using the device listed in /etc/fstab
and will fail to mount it if the entry does not exist in /dev.  I ran
into this exact problem (ad4 and everything) before when I moved my root
disk to a PCI ATA controler.  As I recall the two issues I had where a
bogus fstab entry and not creating all the necessicary entries to get
ad4s1a in /dev.
