I do remember all sort of funky breakage in that area a long time ago but I can't quite remember the details and how I ended up with the current code :-( The one thing to keep in mind is that there was always confusion in the userspace users of the /proc interface as to what offset they had to use... the BAR value or something translated via /proc/.../resources (Normally the latter but a lot of stuff got it wrong ...)
