Here is the last version I posted over a year ago. You were CCed and
provided very useful feedback:

http://lkml.indiana.edu/hypermail/linux/kernel/1205.0/01291.html

Based on your feedback I re-spun them but never gotten around to port
them to recent kernel and post them. The latest (yet unpublished
versions) are here:

https://github.com/gby/linux/commit/04e041327036772383c14ebdc450f522d782f264
https://github.com/gby/linux/commit/f5b8ae815670a289af9ff22ad83da3295472e63c

I'll try to resurrect them, but maybe they'll prove useful as a
reference as they are in the meantime.

Hope it helps,
Gilad
