I've been using "boot int:\vmlinuz" for all of my 1.75 kernel work, and
it's been working fine.  What do you see on serial?

last:\ maps to whichever device the olpc.fth was loaded from, so that
you can write an olpc.fth that doesn't need to know ahead of time
whether it's going to be put on an SD card or a USB stick or whatever.
