Personally, I would speculate that a standard surge protector "helped"
the surge get on the data line by shunting the surge onto either the
ground or neutral, and then finding a piece of equipment that tied a
digital ground to chassis ground, or otherwise used chassis-ground as a
reference.

I've been looking at the units from brickwall.com for my home theater. 
They have an article on the very effect I'm describing at
http://brickwall.com/grndcur.htm

Granted, the link is an advertisement, but I've read seriously good
reviews on this product as compared to a standard MOV-based surge
protector.

On a totally unrelated note, but just to keep this Linux-centric, Chris
Cox was right about the framebuffer being the source of my memory
problems with my GeForce4.  The reason I couldn't boot in anything but
framebuffer mode had to do with some strangeness with my rc.sysinit
(stock Mandrake 8.1).  I still don't know what it was, but everything
started working after I added an echo "I'm here..." in there to see if
that was really where things were going south.  I'm guessing some hidden
character that the fbconsole didn't mind but that the real console minds
was in there, and I got rid of it when I added my trace output.  Weird. 
Also weird: I went up to 2.4.21, and my PS/2 mouse wouldn't go unless I
used the usb-uhci driver (as opposed to the uhci driver)--it's not even
a USB mouse.  That one *really* threw me for a loop.  Actually, it has
the option to be USB or PS/2 with one of those converters--and I've
always been using it as PS/2 (still am).  I've now compiled up a
Win4Lin-equipped kernel and am getting ready to try out Win4Lin so I can
run TurboCAD, BassBox Pro, XOver Pro and a few other things I'd like to
use on something other than my laptop.  Cheers!
