If this bug is really so difficult to fix (I understand about the extreme cases), why not provide an interface which allows for only a subset of font sizes/colours/whatever? Say sizes 6 to 18 or whatever are valid. I can't think of a case where you would want extremes beyond that level.
As for where the UI should reside i guess the best place would be in the appearences application under the fonts tab, or create a new tab for notification settings. (that seems even better to me and an extremely obvious location for it to be.)
As for what it can look like I will leave that up to smarter people.
