What applications care about the internal data structures of the kernel
driver? What can those applications do with that information? What
happens when you have a 64bit kernel on a 32bit userspace? How about
endian issues on different processor types? That sounds like a
nightmare to even consider getting correct...

Anyway, I'll move them to debugfs, thanks.
