Seems like one would need to dig a lot on b.m.o to find all the "remove xyz" and "change xyz" and "do xyz" bugs/patches (including those that relate to gtkmozembed) that would need to be forward ported or otherwise handled.

But, assuming we can track all those down and we can triage all the "local" patches in the Maemo source tree (the ones in microb-engine_20100401-1.9.2-5.2+0m5.diff.gz that get applied as part of the build process through quilt or whatever it is) I think we might actually be able to pull this "update gecko to something recent" effort off
