Currently the only Debian architectures which doesn't use
initramfs by default are the MIPS architectures.  And I understand
that most of the boot loaders for MIPS can actually support an

We have a policy for kernel and initramfs hooks
that should allow that sort of thing to be done without the need
for specific support by the kernel or initramfs packags.
