Uxcell have revamped their download site:

They've even added an idiot proof movie showing how to upgrade the firmware. Probably especially for me, as they don't believe me when I try to explain that the file for the FMP 1.5 is wrong.
There's now 2 firmware versions in this zip file:

but both still have a screen size of 128 x 160. Should be 128 x 128?
