Yep, I can reproduce this.  Patch applies with "git apply",
"patch --dry-run -p1" accepts it, "patch -p1" fails.

 $ patch --version | head -1
 GNU patch 2.6.1.85-423d
 $ cd ~/src/linux-2.6
 $ git checkout 2bfc96a12
 $ git clean -fd
 $ wget http://download.gmane.org/gmane.linux.ports.sh.devel/8747/8748
 $ patch -p1 --quiet --dry-run <8748 
 $ echo $?
 0
 $ patch -p1 --quiet <8748 
 2 out of 2 hunks FAILED -- saving rejects to file include/linux/clkdev.h.rej
 $ echo $?
 1

Andreas: ideas?
