OK, I've done some more experiments.

using ifconfig XXXX up makes no difference. I think the reason has to do
with the following:

This is a CardBus card not a PCMCIA card, so it's PCI not ISA. This means
that the PCMCIA sub-system doesn't know about the card, instead it's managed
by the hotplug system.

So, I tried it out as (effectively) a static card. I removed the hotplug
references from /etc/network/interfaces and used ifscheme as if it was a
normal pci card. After a reboot the card worked, it switched schemes ok and
behaved up to the point where I tried removing and re-inserting it, at which
point as expected it failed since hotplug didn't know about it in the
interfaces file.

So my problem seems to be that the hotplug system and the ifscheme system
are incompatible somehow - time to talk to the developers about that.
