I think it can be a problem in network configuration.
The reason is that the X server (or some other component in
the boot process) tries to resolve the hostname through the
network connection. This may take quite a long
timeout if no network is enabled...
What to do:
1. define some hostname in /etc/hostname
2. make sure it is exactly found in /etc/hosts and resolves to 127.0.0.1
3. define all networks not to block the boot process /etc/network/interfaces
It could also be some issue with the depmod database. Try
depmod -a to rebuild.
