there was a benchmark linked from lwn a couple weeks ago for reiser,
ext2, ext3, xfs, jfs and vfat.  jfs was clearly the slowest (well vfat
was slower but..) xfs was fastest in most tests.

yaboot only supports ext2, 1.2.3 allegedly supports reiser.

yup yaboot can't read jfs, so you must have an ext2 /boot partition,
rtfm for how to correctly setup /etc/yaboot.conf, or just run
yabootconfig and it will generate a valid one.
