Ah. Would it work to use by-path persistence? That's not supported in the book or by the udev developers because (e.g.) USB devices change their paths way too often. But if these laptops only have one PCMCIA slot, then that might work. I had a preliminary by-path patch for udev somewhere, let me see if I can find it... Ah: http://marc.info/?l=linux-hotplug-devel&m=117141213806593&w=2 however, reading it again, I said that I didn't think it'd work with PCMCIA devices. If I knew how those devices showed up in sysfs, I could probably add it (otherwise you could just treat this patch as a starting point).
