What about cvtss2si for float to integer casts/truncs? Even if you
don't care about alignment it'll be faster (Off course assuming you do
at the least align on 4 bytes).

I think that's the best route to take. Even better, if building
Thunderbird compatible code becomes an option at compile time, we
could use 3DNow code. I think a solution using pf2id will be faster on
Thunderbird than the current code.

Downside would be seperate binaries, upside would be performance gains
on all platforms.
