Could you try a more recent kernel, please?

It should work already... and on arm and recent kernels, it should suffice
to use dump_cis from pcmciautils right after booting.

They should be -- at least, I'm not sure that 2.6.10 already has the proper
patches to manage static sockets independently. Maybe you could share the
driver (GPL?) to this list so that we can hunt the bug?
