There are 1394 express card interfaces. No idea about linux support. http://www.expresscard.org/web/site/cons_wtb.jsp#1394
Jesse hit it on the head. Expresscard is FINALLY starting to get to a point where I no longer consider it a LARGE detractor to have it instead of PCMCIA. But also as Jesse pointed out, I have no clue how good the linux support of said cards is.
