And with net-next we might even be able to get past that magic limit? 
net-next is linus-latest plus the latest and greatest networking bits:

 $ cat .git/config

 [remote "net-next"]
	url = git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next-2.6.git
	fetch = +refs/heads/*:refs/remotes/net-next/*

... so might be worth a test. Just to satisfy our curiosity and to 
possibly close the entry :-)
