followup to kernel-source issue

[Joe Pruett <joey clean q7 com>]

i finally figured out that to get the kernel-source rpm to update with 
apt-get, you have to:
rpm -e kernel-source
apt-get install kernel-source#2.4.20-37.9.legacy

given that you can actually do kernel upgrades via the RPM::Upgrade-Kernel 
option, it would certainly be nice to have a way to get the source
updates automatically as well.  even if it does like the kernel and does 
an install instead of an upgrade.  i've peeked at the lua scripts and 
don't see any obvious way to make them get the sources if already 
installed.  am i just out to lunch here?
