Clever.

Extremely clever.  I'll have to remeber cool tricks like that when I'm
working with my own server...

Oh... that makes sense.

I'm actually not certain that I have the kernel built and installed. 
I tried the make install command, but I'm still not certain that I've
done this all correctly.  At this rate, I may try and re-install KDE
and stuff to see if it's no longer a problem with the kernel.  Is
there a way to see what's currently compiled in or modules
enabled/loaded in the kernel that currently running?  If there is,
then I could very quickly diagnose where the disconnect is.

Yeah, but I've been using the "make install" command, so I'm not
totally sure if what I'm doing is even effective.

So I'd add something like

Yeah, nVidia supplies proprietary closed-source drivers, don't they?

Oh.  I just have ADD.  My pills in the morning shut me up, the ones in
the evening shut me down.  When I forget to take my morning pills... 
yeah.  I'm not so bad as I am Mr. Comedy-Central.
