Thanks for bringing me back on the floor, guys. Yes, some things have
To build an ECOFF kernel, which can be booted via TFTP or via Ultrixboot
you have to type "make boot" and you'll find vmlinux.ecoff in
arch/mips/boot. Yes, elf2ecoff has been hacked to work for DECstations too
:-). addinitrd unfortunately does not work. No initrd at the moment.
Another point (cited from the Linux/MIPS-Howto):

Self compiled kernels crash when booting.
When I build my own kernel, it crashes. On an Indy the crash message
looks like the following; the same problem hits other machines as well
but may look completely different.

PANIC: Unexpected exception
This problem is caused by a still unfixed bug in Binutils newer than
version 2.7. As a workaround, change the following line in
LINKFLAGS = -static -N
LINKFLAGS = -static

On the DECstations this look very much like:
[Numbers or whatever printed]
This DECstation is a DS500/1xx
[and then nothing]
and then return to PROM prompt.

Besides your changes to declance.c they are already in the CVS :-)
These are not easy to integrate but I am thinking about possible solutions.

That's indeed the most interesting part...
