Are you sure?  If you leave all the source, but comment out the single 
line that calls initmouse, does this prevent the program from hanging?

This is wrong: ES:DX should point to the callback address, like this:

   regs.x.es = callback_info.rm_segment;
   regs.x.dx = callback_info.rm_offset;

That's what the FAQ says: make exactly the same call as you did in 
initmouse, but with the mask set to zero.
