For what it's worth: Just had the same issue with Ubuntu 12.04:
"The mainproblem for me is that the keyboard is not working there, i can not press "y" to say "boot it anyway"."
This is very annoying.
I can continue boot by typing "return 0" into the maintenance console. But there is no way to keep the server automatically booting. Even "bootdegraded=true" does not help.

This is very, very annoying.
