It probably won't unless magic happens with Cairo. I've run some tests
and it's out-of-the-question without any special tricks at least.
Although my tests didn't exclusively prove that it's the FP api that
kills it (it crawled in an area that should not have anything to do
with FP AFAIK).

I don't think it's feasible for Maemo to start requiring a FPU either,
the non-FPU  ARMs are too popular in embedded systems.

OTOH, nothing prevents replacing the Gtk+ for systems that have an FPU
(barring incompatible patches, but those are being migrated where
possible).

User would notice that Fox looks butt-ugly :)

It's easy to say "or whatever", but you'd really need to prove the "or
whatever" to be worth it. Gtk+ seems to do well enough on the machine,
without major drawbacks (if there were, it wouldn't be used, right?).
It's not like Gtk+ was chosen on a whim (I hope ;).
