You can use our SELF package as  a  model  to  build  custom  ramdisk
images (see ftp://ftp.denx.de/pub/LinuxPPC/usr/src/SELF/).

Are you sure it's executable, i. e. it really  runs  in  the  ramdisk
environment?  You  can  test  ramdisk  directory  trees  easily using
"chroot".

Without more information about how you generated  your  ramdisk,  and
