But the initramfs seems not to be able to mount my nfs share.

Your first attempt seems to be wrong because the full path is not specified.
Your second attempt seems to be that there is a mismatch in nfs versions: The initramfs loads version 4 but the server only serves version 3.
Probably this might help:
https://help.ubuntu.com/community/SettingUpNFSHowTo
You might try to compile the TFTP-Served kernel with nfs-3-support, see lsinitramfs initrd.img-3.5.0-25-generic
to check what's inside.
But when I try to mount my nfs share remotely I can mount with nfs V4: mount -t nfs4 192.168.0.3:/nfsroot /mnt.

Maybe issue with the files, did you use cp -ax
to copy the files from the DVD/image to NFS. See http://ubuntuforums.org/archive/index.php/t-921313.html
Or, it will automatically unmount the given NFS share when it doesn't find the kernel stuff it is looking for.
You might need the boot=casper or similiar. Check your NFS directory structure. dirname find /nfs -type f -name "*linuz*"
