So I installed Ksplice on Ubuntu 10.04:

# download the installer
wget https://www.ksplice.com/uptrack/dist/lucid/ksplice-uptrack.deb
dpkg -i ksplice-uptrack.deb

# install dependencies
apt-get install -f

# set auto-updates
vi /etc/uptrack/uptrack.conf
autoinstall = yes

and...?

Question: This means that if there is a minor/major Kernel update, then Ksplice could install it without asking, and I really don't need to reboot my computer anymore? (until 2013-04 according to: https://en.wikipedia.org/wiki/Ubuntu_%28operating_system%29#Releases)

Ksplice allows you to apply patches to a running kernel without rebooting the system.

It freezes your kernel execution momentarily and points the routines that are modified to the new "patched" routines. Once this has been re-pointed, it resumes your kernel execution.

Most /minor/ updates would probably be patched in this method but any significant changes would still require a reboot. Since most security patches are considered minor adjustments, this would work. Major updates would require a reboot regardless.
