No sarcasm intended at all! I thought it was a really cool idea for
machines I do boot frequently (laptops).

If you are using one of the pre-packaged 2.4.x kernels from Debian
then it will be modular. During boot you will see a "Calculating
module dependencies...." message followed by much disk whirring. For
me, this is the single slowest step during a boot. I just measure it
with a stop watch (actually, I count seconds ;-)
