It does contain the file with a slightly different name for some reason
(note, we're talking of the content of the source package here)...see:
http://archive.ubuntu.com/ubuntu/pool/main/u/udev/udev_113-0ubuntu16.diff.gz

Only problem is...Ubuntu's version of initramfs.premount doesnt include
the patch that Debian's udev does...this is the relevant part from the
diff:

So there's your problem. Ubuntu's udev has no support for the necessary
boot parameter. This needs to be fixed in Ubuntu. You might want to refer
to Debian bug #401916 and its dupes if/when you talk to Ubuntu devs.
