More debugging tools (and docs!) are always welcome IMHO.

Searching the mailing lists doesn't turn up much, so I assume no one has
tried it:

I'd say go for it!  If they are mostly written in C then you probably
don't have to package a lot of transitive dependencies.  Looking in
gnu/packages/linux.scm could be a good starting point for packaging
kernel related tools.
