Do you use a customized kernel? If so, I asume you must compile in at
least ATA/IDE/MFM/RLL support and you will probably also want to
compile in ENHANCED IDE/.... disk/...

I have yet only experiences with one client 8Mb swapping over NFS at
10 Mbit. But I would say that there is a *lot* to gain by using a
customized kernel. My experiments with minimalistic kernels are almost
done, and you can get a .config for 2.4.9 with the NFS-swapping patch
at http://sociologi.cjb.net/ltsp/minimal_1.0.cfg

N.B. It does not include the ATA stuff mentioned above, nor initrd, so
you must compile in drivers for your NIC.

Since I have mostly older terminals, with 10Mbit ISA cards, and lot of
small harddisks, I too would be interested in a local swap patch to ltsp.
