OK, so that means that the initial process is dying and being
One thing that could well be a problem: is the existing filesystem
using the old arm ABI (OABI), but your new kernel has only been built
with new (EABI) support (CONFIG_AEABI=y but not CONFIG_OABI_COMPAT=y)?

yes. You can make a debian rootfs (assuming you have space) by using
multistrap or debootstrap or cdebootstrap. Here is a page giving
details: for multistrap: http://wiki.debian.org/Multistrap
for debootstrap http://wiki.debian.org/EmDebian/DeBootstrap
To have it work you will need to know a few things about your board -
which filesystems to mount in /etc/fstab, which ports to add to
/etc/securetty (allows root logins), which devices to run a getty on
(in /etc/inittab) and which modules to load for e.g. networking to
work, and a few others like /etc/hostname and /etc/hosts. Those files
may well need modifying from the defaults in order to make a rootfs
