Thanks for your feedback, Erik!  I do have a question below...

The kernel I am using is the kernel from the DVD ISO as it is
downloaded from freebsd.org.  How do I determine what modules have
been enabled and disabled in that kernel?  I am under the assumption
that NFS is compiled into that kernel.  We can install 8.2-RELEASE
with this kernel in VMs, but not bare metal.  Is there an explanation
as to why an NFS enabled kernel would work inside a VM, but fail on
bare metal?
