So (if I understand currectly from the little I know about this), a bit
sadly, if there were sutiable flex and bison dlls these could be used
instead (if Davids specials were backported too) and would be quite a
bit faster.
This does not relate to the general question of loading dll:s. This is a
special case that I suppose Richard would approve. (I have no idea, but
I guess there are no flex and bison dlls availabe, or are there?)
However for new languages all this requires also writing language
specific bison grammars. Is this perhaps be a big job that just a few
person have insight in how to do?

nxml-mode does that, but on its own of course.

Great. Then we can hope for that it is easy to get started using CEDET.
