I see no way to speed up the 2.x FPC significantly only by stripping 
something down or whatever. The whole 2.x design is geared towards 
portability and maintainability, speed is only 2nd level goal (and being 
honest, self compilation in ~10 sec even on my >5 year old Core 2 Duo is 
not that bad ;)).

The only approach I see to speed it up is to kick the whole back end and 
generate directly some close to i386 intermediate code directly in the 
parser.
