okay, it worked, thanks Janos - here's that summary.
If your module utilites (depmod/modprobe/insmod etc.) oops with
the latest kernels. (I first observed this behaviour with 2.1.24, but it
is definitly still there with 2.1.25).
1. Ensure that have the lastest modutils (modutils-2.1.23.tar.gz) compiled
and installed.
2. I've been told to upgrade to "at least" binutils 2.7.0.4 but I only
found binutils-2.7.0.3 in packages/GCC on tsx-11, however there was binutils-2.7.0.9
in private/tofu, so I tried that.
3. If your objdump from 2.7.0.9 stops recognizing the -k or --raw options,
drop encaps (I found mine at /usr/bin) into the bit bucket or rename it
and try again.
