@davidfor: Thanks for the quick recap, I did not remember which method did what

Yeah, running fbink manually in a shell will save you *tons* of time

.
For the bottom corner enthusiasts, don't forget that you can pass *negative* values (to x & y; and top & left for opentype), which should help position stuff on bottom edges without having to know the screen resolution...
EDIT: I don't recall if this is exposed in miniclock, but FBInk now supports setting the opentype size in pixels, which makes what I detailed in my previous paragraph even more trivial, since everything is now in the same unit, so you won't have to figure (or compute) the point to pixel conversion yourself

.
(Although, you can: px = dpi/72 * pt).
