do you know of which ones exactly? I was looking into using an old kindle for such a think, but couldn't figure out a straightforward way of pushing data onto it

The Sony ones are pretty hackable

Kindle is one of the harder ones. The Barnes and Noble Nook is android-based and easily rootable: http://forum.xda-developers.com/nook-touch

NB it runs android 2.1 though. Is there even a VNC viewer that runs on an android version that old?

For devices which do have a VNC viewer, is it possible to periodically (e.g. every 15 mins) wake up the device, refresh the screen via VNC, then power off or switch into very low power state running only the timer?

Sony PRS-Tx (I think all 3). Seems like they all used Gingerbread, but for simple apps (e.g. just pulling a web page or text) that should be ok.
