How to prepare a bootable USB drive for collecting power logs from
multiple XO-1, XO-1.5 and XO-1.75.

Note: not widely tested.  It uses OpenFirmware functions to write files
to USB drive, and in the face of minor filesystem corruption these
functions have been known to make the corruption far worse, to the point
of losing files.

Testing of FAT filesystems is especially needed, with an image of the
filesystem taken before running the program.

Recently verified FAT filesystems have not shown any problem.
