I just tried it out on my home PC (which runs XP) and it worked fine. 
I did notice that I had to switch the mode on the monitor (it has 5
modes apparently) so changing it to #2 DVI-D made it work. D-Sub was
#1 and what I used for the VGA connection.  I didn't realize this
earlier so it may actually work on my laptop (I'll try this in the
morning as I'm signing off shortly).

I believe so.  The bios must be a special one for the Dell XPS laptops
as it has a lot of options and power saving is one of them.  Also
video expansion was another but I didn't know what to make of that

I don't have a knoppix CD but I probably should (can you tell I'm not
that skilled with Linux?;)).  I'll burn an image tomorrow of it.  I
also have realized that it's been a while since I backed up my data
(though all my important code is in subversion at my company's
datacenter).  That's another thing to do tomorrow.  Thanks for the
