Oh, sorry! I thought it wouldn't have used the option...
Thanks for this hint!

But I've another important fact:
I've tested linux-3.1 and the behaviour is the same as in linux-2.6.39.4 with the difference that eth0 seems to be up when NFS tries to mount NFSROOT. So I see no reason why the kernel can't send the mount request (I see no request in wireshark).

So now I'll enable more debug output in 3.1 and send you the result like I've done it in my last email for 2.6.39.4...
