Well, the compile phase can. Especially if the first time you try to
compile the kernel with EXTRAVERSION=`git describe` which force almost a
full rebuild every time...

But the worst problem is that a full recompile, with a distro .config,
will take hours on my 2.66GHz/CoreDuo/1G ram. Trimming down .config is
fundamental to be able to bisect effectively, but it's not an easy thing
to do for an unexperienced user (and a painful one for all the rest of
us).

What would be an invaluable help would be a tool that generates
a .config with all the modules and subsystems I am using *now*. Should
be possible in principle by parsing KConfig and Makefiles and using as
input the current .config and lsmod... is it possible to map the kernel
object name to the option enabling it?
