The way I've found to do a PCMCIA install most easily was 8 floppies: 2: standard boot+root 3: base.tgz 3 disk set 3: pcmcia-2.3.18_2.0.7.deb, then dpkg --split kernel-image_2.0.7
You can probably fit the last 3 onto 2, the pcmcia code is small and kernel-image is only a little bit larger than one floppy. I could only find the kernel-image_2.0.7 on master.debian.org in Incoming, though, which implies that it should show up *somewhere* soon but may be hard to find in the meantime. (You don't need special support for pcmcia network cards in the kernel -- the pcmcia package ships with the appropriate new modules (and everyone uses the 8390 anyway :-)) As for compiled-in ether cards: look in the "special-kernels" directory with the boot disks for alternate boot disks; I don't know if there is documentation other than the config files there to tell you which one you want.
