Hmm, I'm using original adapter, but who knows if it's okay to use...

That seems to be side effect of machine under load (it has gpio keyboard).

The zaurus actually is AFAIK unable to run from battery when connected to the external power, so weak power line may explain some of the strange behaviour.
