yep, this is exactly the plan, but with a bit more flexible 'syscall numbering and parametering' interface. Remember, we might want to have several future iterations of this, even if it costs a few cycles in the entry code. I'll re-post the patch (with additions, the current one is mainly a proof of concept thing showing the major benefits and design elements) for 2.5 once the tree opens, but i think now lets concentrate on 2.4 :-)
