Off the top of my head .....

Get the guy at the data centre to get a 5.x or 6.x installation CD.
He should boot with it and choose the Fixit option, and select the
live filesystem on CD.
After that, he will be dropped into a shell and the following steps
will work:

fsck -y /dev/da0s1a (change to the correct slice name!!)

Once that is complete:

mount /dev/da0s1a /mnt
vi /mnt/boot/loader.conf
save changes

Exit the Fixit mode and reboot, removing the CD, and voila!
