Too true. Considering that I need (want) lkm's to work, are there technical
reasons that make getting modload to do ECOFF unachievable (by me, not
_you_ 8-) ??? I guess the question I'm asking is: does the concept of
modload work with ECOFF files?

And is this likely to be less or more difficult than getting gdb to work
on NetBSD/Alpha? 8-)

Is the place for all these #ifdefs modload.c, or arch specific files?
