Yes, it does work. I was copying several gigs from one partition to 
another and in the meantime copying some data to another computer via a 
100Mbit link and I didn't encounter any problems.

Since I use kernel 2.6.11-rc2 with your patch, I sometimes get a lot of 
very strange messages in /var/log/messages and on the terminal I'm 
currently working with. I mean something like this:
