Another option, depending on what IP address(es) you're using, is to set
up a DNS server (bind) on your host (or somewhere on your network, if
you're so lucky) which can provide the FQDN of your host.  I did that with
a diald'ed box (it was already supposed to be a primary nameserver for the
domain, but I made it a secondary for the reverse domain of both the
network card and the modem's IP addresses) and solved the boottime delay
and error messages.

Holler if you'd like help with this fix.  It would probably make other
things faster/easier for you, also.
