Humm, I haven't had this problem on my machine. What panic message
do you get?
To mention; a netbooted 3100/m38 can easily allocate 3 times of the
interna memory and swap over NFS without crashes here.

Yes, and that was because of that the recommended mach way when having
no page reference bits would break the swap system. I fixed this by
emulating the page reference bits with the (otherwise unused) valid bit.
