Wrong. I have not done anything by hand relating to kernels. I think
the problem arose originally when I first installed Debian. I installed
Debian 1.1 after it had just come out. The kernel it provided was 2.0
hot off the press (so it could claim to be the first distribution with
the 2.0 kernel). However the source package that went with it was
the 1.99.7 one. For some reason I don't think it installed properly
back then. I didn't worry about it at the time as I had no need to
"roll my own" kernel and I had other difficulties to worry about.
I have upgraded my system a number of times (currently 1.3) and each
time the problem with kernel-source-1.99.7 has remained. It's only
recently that I've tried to fix the problem and it seems I can't.

I have included it at the end of the message.
Thanks.
