Hello, attached is the patch ported to 2.6.28, note that this is my very first
time in c coding, then this may be an ugly piece of code (but at least works
for me)...

No, the reason is the polling code as already discussed on this list, then the
patch is only for use of who want to apply it himself without any support...
