FONT_RAMP only applies to books in KF8 format, not MOBI or KFX. Any books purchased from Amazon and delivered to a device running 5.8.7 will most likely be sent in KFX format. Check the format of your book if FONT_RAMP doesn't work for you.

(The 5.8.7 firmware has some code to support CONTENT_FONT_RAMP as the equivalent to FONT_RAMP, but for KFX format. Unfortunately, a debug flag that is set to "false" prevents it from actually functioning in the released firmware.)
