dump_cis doesn't. It says "no CIS present". I have bad feelings about
this.

Hmm. "PCMCIA Serial device support" is enabled in the kernel
configuration and CF modems are supported, so I guess there shouldn't be
any reason for them not to work?

However, having looked at the default kernel config for this
architecture (it's called Sharp "Husky"), "8250/16550 and compatible
serial support" is not enabled -- would that make a difference?

Hmm. I'll try -- but I'm afraid the Zaurus people will say this is a
pcmcia problem :-)

I'd appreciate any help. Please let me know if there's anything else I
can do.
