Linux-generic is just a wrapper that pulls in the latest kernel. The actual
kernel packages are called differently and depending on installation are header,
image and modules. But usually you keep the previous kernel and can select it
from the grub menu (there should be descriptions out there how to access /
enable that).
Also, if not already done, you should report a bug about the non-working
touchpad by calling "ubuntu-bug linux" when running the kernel that does no
longer work.
