Kernel update process?

[Danny O'Brien <dannyo@steinrogan.com>]

Sorry to have to post to ask for help on this basic task, but I can't 
find a step-by-step kernel replacement procedure anywhere on the Debian 
site. I've digested the Dwarf's Guide also, without revelation. Maybe 
I'm not hunting properly?

We're running kernel 2.4.18-bf2.4 -- is there a more recent version? 
I've done a grep-available -P kernel|grep ^Package|sort, but the 
results don't show a more recent version than 2.4.18.

I'm familiar with "apt-get" -- can I use apt-get to update the kernel? 
If not, what's the proper procedure?

Thanks for any assistance,
