I think the work probably would have been better invested in 
implementing an internal JIT compiler using the existing hooks as 
Thorsten explained.  This would work on all x86 systems (and for Mac an 
implementation already exists).

BTW your page does not say which optimizations you used for compiling 
the patched version.  To me it seems quite unlikely that you always get 
a speedup, there is also some overhead introduced by calling an external 
library.

None the less an interesting idea of course.
