I see no reason not to add the patch (assuming it works, I haven't tested 
it). Maybe add a target "prepare-bulk-cache" that runs bulk-cache, and 
then prints a list of all files one has to copy over - the above list in 
an expanded form will do, but people can't handle ${INDEXFILE} etc. to 
cp(1).

Oh, and this should definitely be documented in the pkgsrc guide!

I think adding a section "Preparing bulk build on slow machines" before 
"5.3.7. Building a partial set of packages" would be the right place.
Basically a description of the "why" followed by 
"cd /usr/pkgsrc && make BATCH=yes prepare-bulk-cache" && a description of 
how to copy things over (maybe store the filenames in a file?) should be 
enough.
