I guess the fact is that the Nokia N900 proprietary userspace has
never worked properly with the mainline kernel without severe patching,
so you cannot really talk about any regression. If you cannot fix
those programs, you could still probably emulate the old Nokia kernel's
/proc/cpuinfo by providing some text file and bind mounting it, no?
