The instructions on how to use the kernel-package stuff didn't make
much sense to me. How/why is that any easier then compiling directly
from source, the standard way?

I downloaded the standard 2.4.19 sources from kernel.org, compiled and
all is running with the new RAM being recognized. Thanks for the tip.

Now that I am running 2.4.19, is there anything specific that I should
watch out for?
