So that pretty much put a damper on my night since I was in a similar accident, but worse, like 12 years ago while off roading with my father (he used to race sprint cars and baja before he went into the Air Force, and now regularly goes to NASCAR races to work with pit crews behind the wall or something like that). The last thing I remember was the ground coming at my window.
Anyway, before my change in mood, I was working on some simple power controls for the GPC expansion slots.
Still needs work but it is a start.
to cheer you up, considering your windows pains, and my procrastinaton during finals week, I have dug into my collection and brought up this which describes your situation quite well.
