Well, as I said, I don't really need swap right now,
because the system runs in a diskless setup, basically.
But I thought, swapping on the CF thing (if I need it)
would be faster than via nfs on a 10mbit PCMCIA NE2k card
(especially as I still have system hangs over several seconds
with the "ne0: NIC memory corrupt - invalid packet length 51200"
style messages).

Yes, but that wouldn't be a major problem for me... At
least until I finally have a system running off the CF
card, so that I can actually use the Z50 as a portable
device :)
But perhaps it will be better to buy some CF harddisk
then, even if they consume more power, as I've been told.
