Love the "An ExpressCard-PCIe bridge in the ThinkPad’s expansion bay".
Would you have a picture of the ExpressCard laptop connector?

Before Thunderbolt was common, people attempted to use external GPUs with this sort of expander, but it worked really poorly.
Ran openbsd for a few years like that, the base OS included everything needed. I recall it used 24MB of ram and closer to 30MB if ssh'd in. It was very handy to have a local login when playing with firewall rules.
