There is support for custom fonts in /mnt/us/fonts, we can also run PDFs or websites with embedded fonts. I think I'll dig into this over weekend, but any help will be appreciated.
Amazon is shipping a heavily stripped down (and possibly modified?) old version of libfreetype.

I haven't yet looked what libfreetype is shipping with 5.3.0 but we know that the Touch 5.1.2 version labeled libfreetype.so.6.3.20 crashes when you put DejaVu Sans into /mnt/us/fonts.

KPW 5.2.0 has the same version number as 5.1.2, so it could be worth a try.
