Got Wifi running yesterday (Saturday) in Gentoo on my ThinkPad. So I can use the 802.11b wireless card I bought for my Newton 2100 now with my Thinkpad.
Saw H2G2 with A, Chris and Mar. Disappointed.
Got JPilot working with my CLIE on the ThinkPad too. And Plucker is working too, though not tuned and not coordinated with JPilot yet for automatic data updates.
I suspect the FireWire/USB 2.0 combo PC Card I bought on eBay for my ThinkPad will work in Linux. dmesg output looks good.
