That's what I thought.

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.

looks like you are out of luck.
