FreeBSD 7.3-stable fails to boot under KVM

[Dan Langille]

A bunch of use have colo'd a server at an ISP.  We each run our own KVM 
(I have no other details at present). I've been running FreeBSD 7.3 
inside my KVM (everyone else is running Linux.

I encountered a problem when I tried to upgrade the install from 
7.2-stable to 7.3-stable.

The boot process hangs.  The last thing shown is the memory in the 
system.  I'll copy/paste from /var/log/messages to demonstrate the point 
last thing I can see on the VNC screen.
