I would think people would be more likely to donate if this were on a sticky and it had sufficient cheerleading.
Also, getting more exposure by posting it at hackaday.com and other similar places would help (but as mentioned by moderators at hackaday, they get complaints for any hacks that cost more than a McDonald's Happy Meal).
This is a bummer for the hacking community -- I have taken time to give donations for lots of things I like (I give money to WikiPedia every year)...
Of course, the purpose for hacking is often to spend time instead of money, so supporting a cause would be difficult.
Anyway,
post a sticky in the Kindle Developer's Corner (
with moderator permission) saying you need a broken kindle touch...
P.S. I fixed the "Donate" link above. HTML copied from your "PSN Update Finder" page worked better than trying to hack the POST form copied from your home page into a GET link...
