Is it possible just to recompile libfb and replace it?

Hi there,

When looking at usual oprofile results I see a lot of time spent in
libfb, however I am using FC6 which is compiled for i586 or i686.

Would it be possible to download xorg-7.1 and recompile it with really
agresisve optimizations (auto-vectorization, sse2, -O3,
-fomit-frame-pointer, ...) and just to exchange this single library or
should I expect problems?

Thank you in advance, lg Clemens
