After more discussion on IRC, I *think* this might be a peculiarity
of having / on nand.  On my SheevaPlug, which has / on an MMC card,
this works as expected without any manual intervention (IOW, lockd
gets assigned to port 4045).  On my Netgear Stora (the NFS server)
and my GuruPlug, / is ubifs on /dev/mtd2, and both of them show 
the problem behavior.  I don't know if that's related at all, but
it's something to explore.  However, I must go to bed now, and I'll
not be able to do anything with this tomorrow, but at least I have
an idea to pursue now...
