I'm sorry, but I'm just not seeing the delay show up in the logs. Am I missing something there? What makes you say it takes "ages" to detect? Define "detect".

After one of the latest udates, I had the same problem and found out that during the boot process my PC hangs at "networking".
My workaround was excluding some commands of /etc/network/interfaces.

auto lo
iface lo inet loopback

#auto eth0
#iface eth0 inet dhcp

#auto eth1
#iface eth1 inet dhcp

#auto eth2
#iface eth2 inet dhcp

#auto ath0
#iface ath0 inet dhc

auto wlan0

I am NOT a computer expert but just a user.
I found that this change didn't effect my network connections, both wired and wireless.

I can confirm that unless eth0, eth1, etc are commented out my laptop also takes ages to boot up.

What happens is that the init script tries to start all the network devices that are uncommented. They are mostly configured to use dhcp.
If no dhcp server is available on the network then the bootup will pause until the dhcp timeout is reached.
