That's what I thought. >>> 2.

For Linux the bus doesn't really matter. But again, for your BIOS it does. As far as I understand, that's hardware specific. Some card readers are internally wired to USB which gives you a good chance to boot from it. As far as I can see on the ThinkWiki (http://www.thinkwiki.org/wiki/Category:R61 pointing to http://www.thinkwiki.org/wiki/Ricoh_R5C843), the R61 is different. https://forums.lenovo.com/t5/ThinkPad-T61-and-prior-T-series/Boot-T61p-from-SD-card/m-p/261121/highlight/true#M41072 looks like you are out of luck.
