I have not tinkered much with initrd files on *ubuntu but the process
might be the same.
Essentially the initrd files contain a fs with the modules necessary
to bootstrap specific functionality specific to your hardware.

If the "new" kernel has been installed then it should be possible to
hand craft an initrd file for that kernel  [1].

You can start by copying the initrd file of the "existing" kernel.
Study it and the recreate a similar file with modules from the "new"
kernel.   Hint:  you will need to know the functionality of utilities
like file, gzip, cpio, tar.

[1] you can always extract the contents of the new kernel package (see
dpkg -X|-x) and install it manually.
