This makes perfect sense.

Well, in my case, the difference between the kernel images provided by the following two debs:
linux-image-2.6.26-2-686_2.6.26-17_i386.deb
linux-image-2.6.26-2-686_2.6.26-21_i386.deb
don't differentiate by a release as I understand it, correct?

OK, this is good to know.
thanks for your help!
