Q: How do I compile/install the driver?

The easiest way is to use the version included in the kernel source,
or in David Hinds' pcmcia-cs package.

If you need to install a newer version from ozlabs.org, you will need
the kernel source for the kernel you are currently running.  The
Makefile included with the driver assumes that the link
/lib/modules/<version>/build points to this, and that you are using
the pcmcia modules from the kernel, rather than from pcmcia-cs.  If
that's true, then just unpack the driver tar file, run "make", become
root and run "make install".
