If we want to keep those pda devices in Linux kernel then dropping whatever PCMCIA which is not a storage sounds like sane way. No one is going to use such old PDA as daily tool nowadays. And if they want then 6.6 LTS kernel would work better due to WiFi drivers being still present. Bluetooth CF cards are old, v1.x tech. WiFi is 802.11b unless you manage to get one of those libertas_cs cards but they were rare even when new (I was involved in starting 2.6 driver for it). Camera cards had own out-of-tree drivers at that time.
