My guess would be a problem /etc/hosts file. Can you please post the
output from (use a terminal: Applications|Accesories|Terminal):

cat /etc/hosts

Here is a sample of one of mine:

the ".mshome" is only because I also run samba, so ignore that part and
it can be: localhost <name>

Using the above with Hardy Beta I get a boot of only a few seconds
difference with, and without a network connection on my very old
800Mhz/128MB Thinkpad A21M: 3 min 15 sec without, 3 min 25 sec with. ]
  My other machines are considerably faster on boot, but it's easier to
accurately time the laptop :-)
