nfs mounting will hang a machine on bootup

Had a very strange issue this week with my Freebsd 6.2 server on a p7
kernel compiled on Aug 5. Did a customary reboot on a machine which
has an NFS mount in its fstab. The machine didn't come back up,
could not be reached by SSH, but could be pinged. I drove 1.5 hours
to the data center where the machine resides and discovered that it
was hanging trying to mount the NFS share on the other machine --
looping through a permission denied scenario and never continuing on
with the bootup for the entire 1.5 hours.
I have two suggestions here, whether one, the other, or both make sense:
1) Move the sshd startup before the NFS mounting so that I can SSH
into the machine to fix this issue.
2) If an NFS mount fails after X tries, just continue booting up and
allow the situation to be remedied later.
I apologize in advance if I am missing some obvious parameter. For
what its worth, I followed the NFS setup described in the freebsd
handbook on freebsd.org
