[ALUG] apt-get question

I read some time ago in a Linux Mag article that it was possible to filter certain packages out in apt-get upgrade, specifically an upgrade to the kernel. I'm looking to do just that but as usual, I can't find the magazine or any reference on the 'net. So, does anyone here have any experience of filtering out certain packages, for example: kernel*, apache* etc.. So that upgrades to the kernel and apache are not applied, while all other upgrades are. I'm presuming its some configuration option somewhere in /etc/apt... Any suggestions greatly appreciated.
