Ok, what do you think about the indirect-current proposal then?
I can supply a prototype-patch.

Maybe it is a "balancing issue" on machines with 128MB of memory, but on
8MB machines I see no way to get this to work without making it unacceptable
slow or waste lots of memory (barring radical solutions like replacing the
buddy page allocator with something that is less prone to fragmentation)
