They're not surface mount? That's potentially helpful.

Remember SIPP-module ram? Think 30-pin SIMM modules with pins instead
of an edgeboard connector.

Now, when I was a kid, I recall seeing SIPP module sockets in the
Digi-Key catalog, and I also recall seeing individual pin sockets.
Those pin sockets would penetrate through the board, and then you
could plug some other pinned device into those pin sockets.

Here's the thing; if you could heat up those per-pin sockets (they're
metal, no plastic parts) enough that they would melt solder, then you
could conceivably stick them straight into the solder fill already
sitting on the motherboard pin pads. With only one side of the board
visible. Do that for each of the pads, and you've got something you
could simply drop your header on to.

The caveat is that this would be slightly raised from the original
height, so whether everything would fit inside the laptop afterward is
a question for which I don't have an answer. (Though I'd wager it'd
still work on desktop motherboards)
