@rsm: I vaguely remember that someone fixed the 'running Kindlets on 3.x-on-DXG' thing, but good luck finding that post ;D.
As for donations, besides the links to the Laos Literacy Project, that doesn't ring a bell

(@knc1? @twobob?).
Personally, for various reasons, that's not something I intend to do [accept donations, I mean] (except occasional stuff like covering hosting costs or a drive for a device, or indeed for charities, in our context, I find it kind of iffy, when we're building on a semi-closed system, and relying on the contributions of so many different people, but that's me

.).
EDIT: Well, that was easy. It's linked to in the "Known Issues" section of the KUAL post:

#343 for the gory details and hints on how to make it permanent).
