Yes, check the packages.txt output file from olpc-os-builder, look for
the bootfw or olpc-firmware-q* package version. That firmware is
included in the image and laptops will auto-upgrade on first boot.

It's possible, but it might be a little tricky since you would have to
put appropriate code in your olpc.fth boot script on the USB disk. For
simplicity I would stick with the OS-embedded firmware upgrade unless
that is going to be problematic.
