I don't man pages are necessary. But commenting internal
structures in the kernel and providing rationale is very useful.
I'd rather work on commenting the code (if you can automatically
derive man pages from code, fine; but I'd rather not see two
independent sets of documentation).

Most of the code is very understandable, but we can clearly spell
out what's going on...

I looked at kernel/ the top it says:

* 'fork.c' contains the help-routines for the 'fork' system call
* (see also system_call.s).
* Fork is rather simple, once you get the hang of it, but the memory
* management can be a bitch. See 'mm/mm.c': 'copy_page_tables()'

where's mm/mm.c? (oh, memory.c....)

Pretty much every global variable should have an comment stating
what the reason for the initial values are and what it means...
