Install pcmcia-source.  Read /usr/share/doc/pcmcia-source/README.gz;
it explains how to use kernel-package to build a custom PCMCIA module
package for your newly built kernel.

You'll be able to easily remove it if you decide you don't want it
(say, because you move to a kernel that's actually released).  It's
easier to upgrade it and keep track of exactly what version you have

You shouldn't have a problem installing a new kernel image of the same
version; the kernel proper lives in memory, so even if you repoint
LILO at a new image on disk things should be fine.  You *can* get into
trouble if you install a new kernel and new modules that don't agree
with what's running, since then you could conceivably get into a state
where the old kernel needs to load a module but only finds new
modules.  You should be okay if you promptly reboot after installing
the new kernel/modules completes, though.
