Try adding the ",tcp" to the kernel's "nfsroot=..." parameter, i.e. use 
commandline "root=/dev/nfs rw nfsroot=10.3.67.98:/opt/eldk_4_0/ppc_6xx,tcp 
ip=10.3.67.99:10.3.67.98:10.3.67.1:::eth0:off panic=1".

I recall having similar problems when connecting through an 100/10Mbit switch 
and in our case, the ",tcp" switch did the trick.
