I don't know why your nash sleeps for so long.. it's most likely a bug.
Meanwhile, you have 3 other big sleeps:
* ifup-eth (network card acquiring info from DHCP)
* ntpdate (time sync with network)
* S99local/sleep (not sure what that is)

If you get rid of these, you'll shave off ~12 seconds from your boot time ;)
