I've just played a bit with android emulator (to find out is it worth to build image for rx1950), and it looks like it's impossible to run android on device with 32mb RAM. But it runs smoothly on 64mb... So Google guys lie to you when they say that Android runs on 32mb :)
Anyway, I don't know any environment that runs on 32mb devices except opie. And that's sad, because opie is a bit outdated.
