Thank you so much for this patch! I was a bit worried with this, since a really like my kindle (and it is bought in the US, but i live in Denmark).
I purchased the Kindle to read books (obviously), but also to read academic texts, but these are always posted in PDF and Kindle's default reader has HUGE margins. With this patch I'm easily able to read these text on the Kindle.
Will the margin-patch (which is the only patch I use) work if I install 5.3.3 or should I keep it in flight mode for now?
