If by documentation you mean the paltry comments that prefix each function,
then I don't need to compile anything because I can just read them (not that
it'll help any).  However, after fixing/applying your patch to 2.4.2, I got this
error during the build:

working on ../parportbook.sgml
about to copy cascading stylesheet and admon graphics to temp dir
about to rename temporary directory to parportbook
if [ ! -z " parport-share.jpeg  parport-multi.jpeg  parport-structure.jpeg" ];
then cp  parport-share.jpeg  parport-multi.jpeg  parport-structure.jpeg
parportbook; fi
cp: parport-share.jpeg: No such file or directory
cp: parport-multi.jpeg: No such file or directory
cp: parport-structure.jpeg: No such file or directory
make[1]: *** [parportbook] Error 1
make[1]: Leaving directory `/usr/src/linux-2.4.2/Documentation/DocBook'
make: *** [htmldocs] Error 2

parport-share.jpeg doesn't exist anywhere.

My question is this: I was able to use get_module_symbol in 2.2 to gind the
address of various data structures in the kernel.  With the inter_module stuff,
it appears that I can only use those functions for addresses that are
specifically "exported" with inter_module_register.  If so, then I'm screwed
because the data structures I want are not exported by inter_module_register.
According to a scan of the 2.4.2 source code, it's only used by about two or
three modules.
