s3c2416/s3c2450 was my entry into kernel development, so I have an
emotional connection to it ;-) - and also still hold onto a stash of devices.
Nevertheless personally I don't see myself finding the time to continue
working on those platforms (or the s3c2443-based Openmoko Freerunner
I also still have), because as you said those platforms are so old.
