Ah, then yes :-)
In fact, I already have a set of tools installed (along with "fakeroot",
that "kernel-package") because I'm following Debian Installation Guide
instructions:
http://d-i.alioth.debian.org/manual/en.i386/ch08s06.html
(there is a little bug there. "--revision=" string has to start with a
number or it won't compile...)

Yes, yes... that's what I have been doing. Then I can try your
suggestion, in addition with the new "make localmodconfig" that is
running right now.

I also found very easy to compile a new kernel from whatever source by
using the mentioned package, and in fact, it is suggested in the install
manual so they better remove the current instructions if want people use
another method but until then, I will keep using it :-P

Hum... you mean the one for EDID? I've compiled 3 kernels just fine and
had to do nothing special :-?
