All of the 'simple' code is based on 'prep'.  And the prep/ subdir will
die soon, as the needed changes to sanely 'hook' things into
decompress_kernel has gotten into Marcelo's tree.  What was prep/head.S
is simple/head.S and common/relocate.S.  Please give things a shot in
either a current linux-2.4 tree, or the linuxppc-2.4 tree (IIRC, it
should be rsync'able, if not, ping me off-list and I'll fix it).
